" GENERAL DESCRIPTION
The XC9103/9104/9105 series are PWM, PWM/PFM auto switching /manual switching controlled multi-functional step-up DC/DC converter controllers. Output will be stable no matter which load capacitors are used but should a low ESR capacitor be used, RSENSE of about 0.1 will be required and phase compensation will be achieved. This makes the use of ceramic capacitors much easier and allows for lower output ripple and reduced PCB area requirements. Tantalum and electrolytic capacitors can also be used, in which case, RSENSE becomes unnecessary. With 0.9V of standard voltage supply internal, and using externally connected components, output voltage can be set up freely within a range of 1.5V to 30V. With 300kHz or 180kHz frequencies, the size of the external components can be reduced. Oscillation frequencies of 100kHz and 500kHz are also available as custom-designed products. The XC9103 series are PWM controlled. Control switches from PWM to PFM during light loads with the XC9104 and the series is highly efficient from light loads to large output currents. By using external signals, control of the XC9105 can be alternated between PWM and PWM/PFM automatic switching and so, control suited to the application can be selected. A current limiter circuit is built in to the IC (except with the 100kHz and 500kHz version) and monitors the ripple voltage on the FB pin. Operation is shut down when the ripple voltage is more than 250mV(180kHz version). The operations of the IC can be returned to normal with a toggle of the CE pin or by turning the power supply back on.

" NOTES
*1 *2 Although the IC starts step-up operations from a VDD of 0.8V, the output voltage and oscillation frequency are stabilized at VDD 1.8V. Therefore, a VDD of more than 1.8V is recommended when VDD is supplied from VIN or other power sources. With the XC9105 series, the CE pin also serves as a PWM/PFM switching pin. In operation, PWM control is selected when the voltage at the CE pin is more than VDD -0.2V. On the other hand, PWM/PFM automatic switching control at a duty = 25% is selected when the voltage at the CE pin is less than VDD -1.0V and more than VCEH. The overcurrent limit circuit of this IC is designed to monitor the ripple voltage so please select your external components carefully to prevent VLMT being reached under low temperature conditions as well as normal operating conditions. Following current limiter circuit operations, which in turn causes the IC's operations to stop, the operations of the IC can be returned to normal with a toggle of the CE pin or by turning the power supply back on.

ON OFF OFF
By using external signals, the control of the XC9105 series can be switched between PWM control and PWM/PFM automatic switching control. By inputting a voltage of more than VDD -0.2V to the CE/PWM pin, PWM control can be selected. On the other hand, PWM/PFM automatic switching control can be selected by inputting a voltage of less than VDD -1.0V. With the XC9105, by connecting resistors of the same value (RM1, RM2) as shown in the diagram to the left, it is possible to obtain chip disable with SCE ON and, SPWM ON or OFF, PWM/PFM auto switching at Duty=25% with SCE OFF & SPWM ON, & PFM control with both switches OFF. Note: When operating at VDD -1.8V and below (stepping-up from VIN=0.9V), it is necessary to pull-up to VDD in order to allow the CE/PWM pin reach the VCEH voltage level. Please make sure that the IC is in PWM control (SPWM=OFF) when operations start. If SPWM is ON, there are times when chip enable might not operate.

By the time constant, the CE pin will be chip enable after VDD rise so that IC will be in the stable condition.

" OPERATIONAL DESCRIPTION
The XC9103/04/05 series are step-up DC/DC converter controller ICs with built-in high speed, low ON resistance drivers.

Error Amplifier is designed to monitor the output voltage, comparing the feedback voltage (FB) with the reference voltage Vref. In response to feedback of a voltage lower than the reference voltage Vref, the output voltage of the error amp. decreases.

This circuit generates the internal reference clock.

The Ramp Wave Generator generates a saw-tooth waveform based on outputs from the OSC Generator.

The PWM comparator compares outputs from the Error Amp. and saw-tooth waveform. When the voltage from the Error Amp's output is low, the external switch will be set to ON.

This circuit generates PFM pulses. The PWM/PFM automatic switching mode switches between PWM and PFM automatically depending on the load. The PWM/PFM automatic switching mode is selected when the voltage of the CE pin is less than VDD - 1.0V, and the control switches between PWM and PFM automatically depending on the load. PWM/PFM control turns into PFM control when threshold voltage becomes lower than voltage of error amps. PWM control mode is selected when the voltage of the CE pin is more than VDD - 0.2V. Noise is easily reduced with PWM control since the switching frequency is fixed. The series is suitable for noise sensitive portable audio equipment as PWM control can suppress noise during operation and PWM/PFM switching control can reduce consumption current during light load in stand-by.

The reference voltage, Vref (FB pin voltage)=0.9V, is adjusted and fixed by laser trimming (for output voltage settings, please refer to the notes on page 8). To protect against inrush current, when the power is switched on, and also to protect against voltage overshoot, soft-start time is set internally to 10ms. It should be noted, however, that this circuit does not protect the load capacitor (CL) from inrush current. With the Vref voltage limited and depending upon the input to the error amps, the operation maintains a balance between the two inputs of the error amps and controls the EXT pin's ON time so that it doesn't increase more than is necessary.

This function controls the operation and shutdown of the IC. When the voltage of the CE pin is 0.2V or less, the mode will be disable, the channel's operations will stop and the EXT1 pin will be kept at a low level (the external N-type MOSFET will be OFF). When the IC is in a state of disable, current consumption will be no more than 1.0A. When the CE pin's voltage is 0.65V or more, the mode will be enable and operations will recommence.

Step-Up DC/DC Converters
Output voltage can be set by adding external split resistors. Output voltage is determined by the following equation, based on the values of RFB1 and RFB2. The sum of RFB1 and RFB2 should normally be 2 M or less. VOUT = 0.9 x (RFB1 + RFB2) / RFB2 The value of CFB1, speed-up capacitor for phase compensation, should result in fzfb = 1/(2 x CFB x RFB1) equal to 5 to 30kHz. Adjustments are required depending on the application, value of inductance (L), and value of load capacity (CL). fzfb = 30kHz (L=10H) fzfb = 20kHz (L=22H) fzfb = 10kHz (L=47H) [ Example of Equation ] RFB1 : 120k CFB : 47pF 68pF 130pF RFB2 : 45k (fzfb = 30kHz, L = 10H) (fzfb = 20kHz, L = 22H) (fzfb = 10kHz, L = 47H)
< The use of ceramic capacitor CL >
The circuit of the XC9103/04/05 series is organized by a specialized circuit which reenacts negative feedback of both voltage and current. Also by insertion of approximately 100m of a low and inexpensive sense resistor as current sense, a high degree of stability is possible even using a ceramic capacitor, a condition which used to be difficult to achieve. Compared to a tantalum condenser, because the series can be operated in a very small capacity, it is suited to use of the ceramic capacitor which is cheap and small.
