High Input Voltage 12A PWM Converter With Adjustable Soft Start
• Adjustable Output Voltage from +0.8V to +12V
- 0.8V Reference Voltage
- +1% Accuracy over Temperature
The APW8716A is a 12A, synchronous, step-down con-
verter with integrated 9.7mΩ N-channel High-Side
MOSFET and 5.2mΩ Low-Side MOSFET. The APW8716A
• 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.
• 20mA Low Dropout Regulator (LDO) with Fixed 5V The APW8716A provides excellent transient response and
accurate DC voltage output in either PFM or PWM Mode.
• Power-On-Reset Monitoring on LDO pin
In Pulse Frequency Mode (PFM), the APW8716A provides
• Excellent line and load transient responses
very high efficiency over light to heavy loads with loading-
modulated switching frequencies. In PWM Mode, the con-
