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.

- Discontinuous Conduction Mode in Light Load to Increase Efficiency (VEN=2V)
- Sence External RSENSE (option 2)
General Description
The APW7391 is a dual channel voltage mode, synchronous PWM controller which drives dual N-channel MOSFETs. The device integrates monitoring and protection functions into a single package, provides two controlled power output with under-voltage and overcurrent protections. The APW7391 provides excellent regulation for output load variation. The internal 1.0V temperature compensated reference voltage provides high accuracy of 0.8% over line and load regulation. The PWM switching frequency is adjustable from 50kHz to 350kHz. The APW7391 has been equipped with excellent protection functions: POR, IMON, OCP, SCP, UVP, OVP OTP. The Power-On-Reset (POR) circuit can monitor the VCC input voltage to make sure the supply voltage is valid. The APW7391 adopts either the external power inductor’s DCR or an external accurate sense resistor to sense the output current. The output current information is reported at IMON pin whose output voltage is proportional to output current. During the PWM switching, the APW7391 has OCP and SCP protections. When the load current exceeds the OCP or SCP threshold, the APW7391 shuts off its PWM switcher to prevent catastrophic failure caused by abnormal load or short-circuit. The APW7391 senses its FB pin for output UVP and OVP protection, which is 50% and 120% of reference voltage respectively. When the UVP or OVP occurs, the APW7391 latches off the PWM switcher. APW7391 has over temperature protection. When the die temperature is above 150°C, the APW7391 ceases PWM operation and recover normal operation when the die temperature drops by 40°C. The APW7391 is available in SSOP-24 and SSOP-24P packages, which is compliant with RoHS.

The Power-On-Reset (POR) circuit can monitor the VCC input voltage to make sure the supply voltage is valid. The APW7391 adopts either the external power inductor’s DCR or an external accurate sense resistor to sense the output current. The output current information is reported at IMON pin whose output voltage is proportional to output current. During the PWM switching, the APW7391 has OCP and SCP protections. When the load current exceeds the OCP or SCP threshold, the APW7391 shuts off its PWM switcher to prevent catastrophic failure caused by abnormal load or short-circuit. The APW7391 senses its FB pin for output UVP and OVP protection, which is 50% and 120% of reference voltage respectively. When the UVP or OVP occurs, the APW7391 latches off the PWM switcher. APW7391 has over temperature protection. When the die temperature is above 150°C, the APW7391 ceases PWM operation and recover normal operation when the die temperature drops by 40°C. The APW7391 is available in SSOP-24 and SSOP-24P packages, which is compliant with RoHS.

Features
- N-CH MOSFET: 20mΩ for Low Side
General Description
The APW9105 is a high efficiency synchronous buck converter with integrated 40m/20mΩ of upper/lower power MOSFET and offers 6A continuous current capability. This part is part of the family of converters with a proprietary ANPEC System Phase Shift (ASP) method that allows multiple converters to be daisy chained together while being able to synchronize to an external clock, allowing for a much reduced system noise performance. The ASP pin of the APW9105 can output a synchronized clock to the external clock with a slight phase delay to the next converter such that next converter will not turn on at the same time. Another feature of this part is its ability to automatically optimize its BW (DyncBandwidth) to allow better dynamic response once it is synchronized to a higher external clock. The APW9105 uses a peak current mode control scheme to regulate the output voltage. The internal switching frequency is set at 600kHz while the EN/SYNC pin supports external clock synchronization. The APW9105 also equips a technique: SpeedTransTM, which allows improving transient response without complex external compensation circuits design. VDD bypass pin allows for an external 5V supply to power the internal control circuitry thereby reducing overall system power consumption for better efficiency especially at light load conditions. And PM selection, It can improve the efficiency when the load is light. The APW9105 is also equipped with Power-on-reset, soft-start, and complete protections, over-temperature, overvoltage, under-voltage and over-current of the converter The APW9105 is offered in a TQFN3x2-14 package allowing small size while having an excellent thermal capability for power dissipation.
