General Description
The APW8716AH is a 12A, synchronous, step-down converter with integrated 9.7mΩ N-channel High-Side MOSFET and 5.2mΩ Low-Side MOSFET. The APW8716AH steps down high voltage to generate lowvoltage for chipset or RAM supplies in notebook computers. The APW8716AH provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Modulation (PFM), the APW8716AH 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 low-noise requirements. The APW8716AH is equipped with accurate current-limit, output under-voltage, and output over-voltage protections, perfect for various applications. A Power-On-Reset function monitors the voltage on LDO to prevent wrong operation during power-on. The APW8716AH has external adjustable soft-start and integrates output discharge method for soft stop. A soft-start ramps up the output voltage with programmable timing to reduce the start-up current. A soft-stop function actively discharges the output capacitors. The APW8716AH is available in TQFN5x5-30 (Power PAK).

The APW7089 is a 4A, asynchronous, step-down converter with integrated 80mΩ P-channel MOSFET. The device, with current-mode control scheme, can convert 4.5~26V input voltage to the output voltage adjustable from 0.8 to 90% VIN to provide excellent output voltage regulation. The APW7089 regulates the output voltage in automatic PSM/PWM mode operation, depending on the output current, for high efficiency operation over light to full load current. The APW7089 is also equipped with power-onreset, soft-start, and whole protections (under-voltage, over-temperature, and current-limit) into a single package. In shutdown mode, the supply current drops below 5µA. This device, available in a 8-pin SOP-8P package, provides a very compact system solution with minimal external components and good thermal conductance.

The APW8713B is a 8A, synchronous, step-down converter with integrated 30mΩ N-channel High-Side MOSFET and 9mΩ Low-Side MOSFET. The APW8713B steps down high voltage to generate low-voltage chipset or RAM supplies in notebook computers. TheAPW8713B provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the APW8713B provides very high efficiency over light to heavy loads with loadingmodulated switching frequencies. In PWM Mode, the converter works nearly at constant frequency for low-noise requirements. The APW8713B is equipped with accurate current-limit, output under-voltage, and output over-voltage protections, perfect for various applications. A Power-On-Reset function monitors the voltage on VLDO to prevent wrong operation during power-on. The APW8713B has external adjustable soft-start and built-in an integrated output discharge method for soft stop. A soft-start ramps up the output voltage with programmable timing to reduce the start-up current. A soft-stop function actively discharges the output capacitors. The APW8713B is available in TQFN4x4-23 (Power PAK).

General Description
The APW9211S is a two-channel synchronous mode PWM converter with 4A continuous current capability for one channel and 2A continuous current capability for the other one. Each channel of the APW9211S has independent enable, and it also allows the two regulators to start together by using the same enable signal and the same soft-start capacitor. Although the switching frequency of the APW9211S is fixed at 600kHz. The APW9211S also provides a 180-degree phase shifting technique to minimize switching noise. The output voltage of each channel can be adjusted using an external resistor divider. Other features include UVP, current limit, and OTP. The APW9211S is available in a VTQFN-13 package with small size and excellent thermal capacity.

APW9213
Active
Dual 2.4MHz, 4A/2A Synchronous Buck Converter

Features
  • Input Voltage range : 2.5V to 5.5V
  • 4A/2A Output Current on Channel 1/2
  • Typical 0.6V ±1% Internal Reference Voltage
  • 2.4MHz Constant Frequency Operation
  • Current Mode Operation
  • Internally Compensated
  • Built in OVP, UVP, Current Limit and OTP
  • Low Cost VTQFN3x2-18 package
  • Lead Free and Green Devices Available (RoHS Compliant)
  • Force PWM Mode Operation
  • DyncBandwidthTM Technology

General Description
The APW9213 is a two-channel synchronous mode PWM converter with 4A continuous current capability for one channel and 2A continuous current capability for the other one. 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 converter synchronizes its switching frequency to two times the frequency on the EN/SYNC pin. The APW9213 uses a peak current mode control scheme to regulate the output voltage. The internal switching frequency is set at 2.4MHz. while the EN/SYNC pin supports external clock synchronization. DyncBandwidthTM improves transient response when receiving higher external Synchronization clock. The APW9213 is offered in a VTQFN3x2-18 package allowing small size while having an excellent thermal capability for power dissipation.
