Features
General Description
Adjustable Output Voltage from +0.8V to +12V
- 0.8V Reference Voltage
- +1% Accuracy over Temperature
The APW8713C is a 10A, synchronous, step-down con-
verter with integrated 30mN-channel High-Side
MOSFET and 9mLow-Side MOSFET. The APW8713C
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 APW8713C provides excellent transient response

Mode. In Pulse Frequency Mode (PFM), the APW8713C
provides very high efficiency over light to heavy loads with
Programmable PWM Frequency from 100kHz to loading-modulated switching frequencies. In PWM Mode,
1000kHz
the converter works nearly at constant frequency for low-
Integrated 30mat VCC=5V N-Channel MOSFET noise requirements.
For High Side
The APW8713C is equipped with accurate current-limit,

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).
