General Description
Adjustable Output Voltage from +0.8V to +12V
- 0.8V Reference Voltage
- +1% Accuracy over Temperature
The APW8715 is a 6A, synchronous, step-down converter
with integrated 30mN-channel High-Side MOSFET and
12mLow-Side MOSFET. The APW8715 steps down
Operates from An Input Battery Voltage Range of high voltage to generate low-voltage chipset or RAM sup-
+2.7V to +28V
plies in notebook computers.
Power-On-Reset Monitoring on VCC pin
The APW8715 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 APW8715 provides
very high efficiency over light to heavy loads with loading-
Programmable PWM Frequency from 100kHz to modulated switching frequencies. In PWM Mode, the con-
1000kHz
verter works nearly at constant frequency for low-noise
Integrated 30mat VCC=5V N-Channel MOSFET requirements.
For High Side
The APW8715 is equipped with accurate current-limit, out-

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).
