Features
General Description
Adjustable Output Voltage from +0.8V to +12V
- 0.8V Reference Voltage
- +1% Accuracy over Temperature
The APW8716 is a 12A, synchronous, step-down con-
verter with integrated 9.7mN-channel High-Side
MOSFET and 5.2mLow-Side MOSFET. The APW8716
Operates from An Input Battery Voltage Range of steps down high voltage to generate low-voltage chipset
+2.7V to +28V
or RAM supplies in notebook computers.
Power-On-Reset Monitoring on VCC pin
The APW8716 provides excellent transient response and

accurate DC voltage output in either PFM or PWM Mode.
PFM mode for increased light load efficiency
In Pulse Frequency Mode (PFM), the APW8716 provides
very high efficiency over light to heavy loads with loading-
Programmable PWM Frequency from 300kHz to modulated switching frequencies. In PWM Mode, the con-
1000kHz
verter works nearly at constant frequency for low-noise
Integrated 9.7mat VCC=5V N-Channel MOSFET requirements.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines Greento mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
