data sheet adp1290 theory of operation the adp1290 is a high - side nmos load switch, controlled by an i nternal charge pump. the adp1290 is designed to operate with power supply voltages between 2.3 v and 13.2 v. an internal charge pump biases the nmos switch to achie ve a relatively constant, ultra low on resistance of 4 0 m? across the entire input voltage range . the use of the internal charge pump also allows controlled turn on times. t urning t he nmos switch on and off is controlle d by the enable input , en, which is capable of interfacing directly wit h 1.2 v logic sign als . gnd en vin vout 12529-020 charge pump and slew rate control figure 20 . functional block diagram the adp1290 is capable of 2 a of continuous current as long as t j i s less than 8 5 c. between 85 c and 105 c, the rated current decreases line arly to 1.6 a. esd protection structures are shown in the block diagram as zener diodes. the adp1290 is a low quiescent current device with a weak 1 5 na pull - down current sink o n its enable pin (en) . t he adp1290 is available in a space - saving 1. 0 mm 1. 5 mm , 0 .5 mm pitch, 6 - ball wlcsp . rev. 0 | page 9 of 12
adp1290 data sheet applications informa tion capacitor selection output capacitor the adp1290 is designed for o peration with small, space - saving ceramic capacitors but functions with most commonly used capacitors when the effective series resistance (esr) value is carefully considered . the esr of the output capacitor affects the response to load transients. a typic al 1 f capacitor with an esr of 0.1 ? or less is recommended for good transient response. using a larger value of output capacitance improve s the transient response to large changes in load current. input bypass capacitor connec ting at least 1 f of capacitance from vin to gnd reduces the c ircuit sensitivity to the pcb layout, especially when high source impedance or long input traces are encountered. when an output capacitance of greater than 1 f is required, increase the input capacitor to match it. ground current the major source for gro und current in the adp1290 is the internal cha rge pump for the fet drive circuitry. figure 21 shows the typical ground current when v en = v in and varies from 2.3 v to 13.2 v. 0 5 10 15 20 25 2 4 6 8 10 12 14 input vo lt age (v) ground current (a) i load = 100m a i load = 50m a i load = 200m a i load = 500m a i load = 1000m a i load = 2000m a 12529-021 figure 21 . ground current vs. input voltage (v in ), different load current s (i load ) enable feature the adp1290 uses the en pin to enable and disable the vout pin under normal operating conditions. as shown in figure 22 , when a rising voltage (v en ) on the en pin crosses the active threshold , the vout pin turns on. when a falling voltage (v en ) on the en pin crosses the inactive threshold, the vout pin turns off. 0 1 2 3 4 5 6 0.50 0.55 0.60 0.65 0.70 0.75 0.80 0.85 0.90 0.95 1.00 v out (v) enable vo lt age (v) v en rising v en f alling 12529-022 v out a t 2 . 3 v v out a t 5 .0v figure 22 . typical en operation as show n in figure 22 , the en pin has hysteresis built in to it . th e hysteresis prevents on/off oscillations that can occur due to noise on the en pin as it passes through the threshold points. the e n pin rising and falli ng thresholds derive from the v in voltage; therefore, these thresholds vary with the changing input voltage. figure 23 shows the typical en rising and falling thresholds when t he input voltage varies from 2.3 v to 13.2 v. 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 2 4 6 8 10 12 14 enable threshold (v) v in (v) e n r i s e e n f a l l 12529-023 figure 23 . typical en thresholds (rising and falling ) vs. input voltage (v in ) rev. 0 | page 10 of 12
data sheet adp1290 timing tur n on delay is defined as the interval between the time that v en exceeds the rising threshold voltage and when v out rises to ~10% of its final value. the adp1290 incl udes circuitry that has a typical 2 50 s turn on delay a nd a controlled rise time to limit the v in inrush current. as shown in figure 24 and figure 25, the turn on delay is nearly in dependent o f the input voltage . 12529-024 ch1 2.00v b w ch3 100ma? b w ch2 2.00v b w m400s a ch4 1.04v t 10.40% 2 1 3 en input current output figure 24 . typical turn o n time and inrush current, v in = 2.5 v, c out = 10 f, r load = 100 12529-025 ch1 2.00v b w ch3 200ma? b w ch2 5.00v b w m400s a ch4 1.04v t 10.40% 2 1 3 en input current output figure 25 . typical turn on time and inrush current, v in = 6. 5 v, c out = 10 f, r load = 100 the rise time is defined as the time it takes the output voltage to rise from 10% to 90% of v out reaching its final v alue. the tur n on delay is dependent on the rise time of the internal charge pump. for very large values of output capacitance, the rc time constant ( where c is the load capacitance , c load , and r is the rds on ||r load ) c a n bec ome a factor in the ri se time of the output voltage. because rds on is much smaller than r load , an adequate approximation for rc is rds on c load . an input or load capacitor is not requir ed for t he adp1290 ; however, capacitors can suppress noise on the board. the turn off time is defined as the time it takes for the output voltage to fall from 90% to 10% of v out reaching its final value. the turn off time is also dep endent on the rc time constant of the output capacit ance (c load ) and load resistance (r load ) . figure 26 and figure 27 show the typical turn off times with v in = 6.5 v, c out = 10 f and 100 f, and r load = 100 . 12529-026 ch1 2.00v b w ch2 2.00v b w m400s a ch4 1.04v t 10.40% 2 1 en output figure 26 . typical turn off time , c out = 10 f , r load = 100 12529-027 ch1 1.00v b w ch2 2.00v b w m400s a ch4 1.08v t 10.40% 2 1 en output figure 27 . typical turn off time, c out = 100 f, r load = 100 current and thermal overload precautions th e adp1290 is not protected against damage due to excessive power dissipation and does not have thermal overload protection circuits. to prevent permanent damage , never allow current through the adp1290 to exceed its rated value for more than a few milliseconds. pe rmanent damage can also occur if the output is shorted to ground thermal consideratio ns to guarantee reliable operation, the junction temperature of the adp1290 must not exceed 105c. to ensu re that the junction temperature stays below this maximum value, the user must be aware of the parameters that contribute to junction temperature changes. these parameters include ambient temperature, power dissipation in the power device, and thermal resistances between the junction and ambient air ( ja ). the ja number is dependent on the package assembly and the amount of copper used to solder the package pins to the pcb. rev. 0 | page 11 of 12
