(typ.) pch driver and 0.4 ? (typ.) nch synchronous switching transistor, designed to allow the use of ceramic capacitor. pfm control enables a low quiescent current, making these prod ucts ideal for battery operated devices that require high efficiency and long battery life. only inductor, c in and c l capacitors are needed as external parts to make a step down dc/dc circuit. operation voltage range is from 2.0v to 6.0v. this produc t has fixed output voltage from 1.0v to 4.0v(accuracy: 2.0%) in increments of 0.1v. during stand-by, all circuits are shutdown to reduce consumption to as low as 0.1 a(typ.) or less. with the built-in uvlo (under voltage lock ou t) function, the internal p-channel mos driver transistor is forced off when input voltage gets lower than uvlo detection vo ltage. besides, XC9265 series has uvlo release voltage of 1.8v (typ.). the product with c l discharge function can discharge c l capacitor during stand-by mode due to the internal resistance by turning on the internal switch between v out -gnd. this enables output voltag e restored to gnd level fast. features input voltage range : 2.0v~6.0v output voltage setting : 1.0v~4.0v (2.0%, 0.1v step increments) output current : 200ma(XC9265a/c) 50ma(XC9265b/d) driver transistor : 0.4 ?

(refer to the block diagram below.) an ultra-low quiescent current circuit and synchronous rectific ation enable a significant reducti on of dissipation in the ic, a nd the ic operates with high efficiency at both light loads and heavy loads. current limit pfm is used for the control method, and even when switching current superposition occurs, increases of output voltage ripple are suppressed, allowing use over a wide voltage and current range. th e ic is compatible with low-capacitance ceramic capacitors, and a small, high-performance step-down dc-dc converter can be created. the actual output voltage v out(e) in the electrical characteristics is the threshold voltage of the pfm comparator in the block diagram. therefore the average output voltage of the step-down circuit, including peripheral components, depends on the ripple voltage. before use , test fully using the actual device. reference voltage for stabilization of the output voltage of the ic. (1) the feedback voltage (fb voltage) is the voltage that results fr om dividing the output voltage with the ic internal dividin g resistors r fb1 and r fb2 . the pfm comparator compares this fb voltage to v ref . when the fb voltage is lower than v ref , the pfm comparator sends a signal to the buffer driver through the pfm control circuit to turn on the pch driver tr. when the fb voltage is higher than v ref , the pfm comparator sends a signal to prevent the pch driver tr from turning on. (2) when the pch driver tr is on, the current sense circuit monitors the current that flows through the pch driver tr connected to the lx pin. when the current reaches the set pfm switching current (i pfm ), the current sense circuit sends a signal to the buffer driver through the pfm control circuit. this signal turns off the pch driver tr and turns on the nch synchronous rectification switch tr. (3) the on time (off time) of the nch synchronous rectification sw itch tr is dynamically optimized inside the ic. after the off time elapses and the pfm comparator detects that the v out voltage is higher than the set voltage, the pfm comparator sends a signal to the pfm control circuit that prevents the pch driver tr from turning on. however, if the v out voltage is lower than the set voltage, the pfm comparator starts pch driver tr on.
12/29 XC9265 series operational explanation (continued) by continuously adjusting the interval of the linked operation of (1), (2) and (3) above in response to the load current, the o utput voltage is stabilized with high efficiency fr om light loads to heavy loads. the pfm switching current monitors the current that flows through the pch driver tr, and is a value that limits the pch driver tr current. the pch driver tr remains on until the coil current reaches the pfm switching current (i pfm ). an approximate value for this on-time t on can be calculated using the following equation: t on = l i pfm / (v in ? v out ) to avoid excessive ripple voltage in the event that the coil curr ent does not reach the pfm switching current within a certain interval even though the pch driver tr has turned on and the fb voltage is above v ref , the pch driver tr can be turned off at any timing using the maximum on-time function of the pfm control circuit. if the pch driver tr turns off by the maximum on-time function instead of the current sens e circuit, the nch synchronous rectification switch tr will not turn on and the coil current will flow to the v out pin by means of the parasite diode of the nch synchronous rectification switch tr. when the v in voltage is lower than the output voltage, through mode automat ically activates and the pch driver tr stays on continuously. (1) in through mode, when the load current is increased and the current that flows through the pch driver tr reaches a load cur rent that is several tens of ma lower than the se t pfm switching current (i pfm ), the current sense circuit sends a signal through the pfm control circuit to the buffer driver. this signal turns off the pch driver tr and turns on the nch synchronous rectification switch tr. (2) after the on-time (off-time) of the nch synchronous rectific ation switch tr, the pch driver tr turns on until the current r eaches the set pfm switching current (i pfm ) again. if the load current is large as described abov e, operations (1) and (2) above are repeated. if the load current is several tens of ma lower than the pfm switching current (i pfm ), the pch driver tr stays on continuously. when the v in voltage rises, v in start mode stops the short-circuit protection functi on during the interval until the fb voltage approaches v ref . after the v in voltage rises and the fb voltage approaches v ref by step-down operation, v in start mode is released. in order to prevent an excessive rush current while v in start mode is activated, the coil current flows to the v out pin by means of the parasitic diode of the nch synchronous rectification tr. in v in start mode as well, the coil current is limited by the pfm switching current. the short-circuit protection function monitors the v out voltage. in the event that the v out pin is accidentally shorted to gnd or an excessive load current causes the v out voltage to drop below the set short-circuit protection voltage, the short-circuit protection f unction activates, and turns off and latches the pch driver tr at any selected timing. once in the latched state, the ic is turned off and then restarted from t he ce pin, or operation is started by re-applying the v in voltage. when the v in pin voltage drops below the uvlo detection voltage, the ic stop s switching operation at any selected timing, turns off the pch driver tr and nch synchronous rectification switch tr (uvlo mode). when the v in pin voltage recovers and rises above the uvlo release voltage, the ic restarts operation. on the XC9265 series, a c l discharge function is available as an option (XC9265c/XC9265d types). this function enables quick discharging of the c l load capacitance when l voltage is input into the ce pin by the nch tr connected between the v out -gnd pins, or in uvlo mode. this prevents malfunctioning of the application in the event that a charge remains on c l when the ic is stopped. the discharge time is determined by c l and the c l discharge resistance r dchg , including the nch tr (refer to the diagr am below). using this time constant = c l r dchg , the discharge time of the output voltage is ca lculated by means of the equation below. v = v out e - t / , or in terms of t, t = in(v out / v) v: output voltage after discharge v out : set output voltage : discharge time c l : value of load capacitance (c l ) r dchg : value of c l discharge resistance varies by power supply voltage. : c l r dchg the c l discharge function is not avail able on the XC9265a/XC9265b types.

14/29 XC9265 series note on use (continued) 16. in actual operation, the maximum on-time depends on the per ipheral components, input voltage, and load current. before use, test fully using the actual device. 17. when the v in voltage is turned on and off continuously, excessive rush current may occur while the voltage is on. before use, test fully us ing the actual device. 18. when the v in voltage is high, the pch driver may change from on to off before the coil current reaches the pfm switching current (i pfm ), or before the maximum on-time elapses. before use, test fully using the actual device. 19. when the ic change to the through mode at light load, the su pply current of this ic can increase in some cases. 20. for temporary, transitional voltage drop or voltage rising pheno menon, the ic is liable to malfunction should the ratings b e exceeded. 21. torex places an importance on impr oving our products and their reliability. we request that users incorporate fail-sa fe designs and post-aging protec tion treatment when using torex products in their syst ems.
15/29 XC9265 series note on use (continued) instructions of pattern layouts 1. to suppress fluctuations in the v in potential, connect a bypass capacitor (c in ) in the shortest path between the v in pin and ground pin. 2. please mount each external component as close to the ic as possible. 3. wire external components as close to the ic as possible and use thick, short c onnecting traces to r educe the circuit impedan ce. 4. make sure that the ground traces are as thick as possibl e, as variations in ground potential caused by high ground currents at the time of switching may result in instability of the ic. 5. internal driver transistors bring on heat because of the transistor current and on resistance of the driver transistors. recommended pattern layout (usp-6el) top view bottom view recommended pattern layout (sot-25) top view bottom view
