High-Performance Notebook PWM Controller
Features
- ±1% Accuracy Over-Temperature
General Description
The APW8828K is a single-phase, constant-on-time, synchronous PWM controller, which drives N-channel MOSFETs. The APW8828K steps down high voltage to generate low-voltage for chipset or RAM supplies in notebook computers. The APW8828K provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the APW8828K provides very high efficiency over light to heavy loads with loading-modulated switching frequencies. In PWM Mode, the converter works nearly at constant frequency for lownoise requirements. The APW8828K is equipped with accurate positive current-limit, output under-voltage, and output overvoltage protections, perfect for NB applications. The Power-On-Reset function monitors the voltage on VCC to prevent wrong operation during power-on. The APW8828K has a 1ms digital soft-start and integrates ramp-down control for soft-stop. An internal integrated soft-start ramps up the output voltage with programmable slew rate to reduce the start-up current. A soft-stop function actively discharges the output capacitors with controlled reverse inductor current. The APW8828K is available in 16pin TQFN 3x3 package.

General Description
The APW8833 integrates dual step-down, constant-ontime, synchronous PWM controllers (that drives dual Nchannel MOSFETs for each channel) and two low dropout regulators as well as various protections into a chip. The PWM controllers step down high voltage of a battery to generate low-voltage for NB applications. The output of PWM1 and PWM2 can be adjusted from 2V to 5.5V by setting a resistive voltage-divider from VOUTx to GND. The linear regulators provide 5V and 3.3V output for standby power supply. The linear regulators provide up to 100mA output current. When the PWMx output voltage is higher than LDOx bypass threshold, the related LDOx regulator is shut off and its output is connected to VOUTx by internal switchover MOSFET. It can save power dissipation. The charge pump circuit with 250kHz clock driver uses VOUT1 as its power supply to generate approximately 15V DC voltage. The APW8833 provides excellent transient response and accurate DC output voltage in either PFM or PWM Mode. In Pulse-Frequency Mode (PFM), the APW8833 provides very high efficiency over light to heavy loads with load ingmodulated switching frequencies. The Forced-PWM Mode works nearly at constant frequency for low-noise requirements. The unique ultrasonic mode maintains the switching frequency above 25kHz, which eliminates noise in audio application. The APW8833 has individual enable controls for each PWM channels. Pulling both EN1/2 pin low shuts down the all of outputs. The LDO3 and LDO5 of APW8833 B/C are always on standby power. The APW8833 is available in a TQFN3x3-20 package.

- 250kHz Clock Signal for 15V Charge Pump (Used PWM1 as Its Power Supply)
General Description
The APW8833 integrates dual step-down, constant-ontime, synchronous PWM controllers (that drives dual Nchannel MOSFETs for each channel) and two low dropout regulators as well as various protections into a chip. The PWM controllers step down high voltage of a battery to generate low-voltage for NB applications. The output of PWM1 and PWM2 can be adjusted from 2V to 5.5V by setting a resistive voltage-divider from VOUTx to GND. The linear regulators provide 5V and 3.3V output for standby power supply. The linear regulators provide up to 100mA output current. When the PWMx output voltage is higher than LDOx bypass threshold, the related LDOx regulator is shut off and its output is connected to VOUTx by internal switchover MOSFET. It can save power dissipation. The charge pump circuit with 250kHz clock driver uses VOUT1 as its power supply to generate approximately 15V DC voltage. The APW8833 provides excellent transient response and accurate DC output voltage in either PFM or PWM Mode. In Pulse-Frequency Mode (PFM), the APW8833 provides very high efficiency over light to heavy loads with loadingmodulated switching frequencies. The Forced-PWM Mode works nearly at constant frequency for low-noise requirements. The unique ultrasonic mode maintains the switching frequency above 25kHz, which eliminates noise in audio application. The APW8833 has individual enable controls for each PWM channels. Pulling both EN1/2 pin low shuts down the all of outputs. The LDO3 and LDO5 of APW8833 B/C are always on standby power. The APW8833 is available in a TQFN3x3-20 package.
