APW8715

APW8715 High Input Voltage 6A PWM Converter With Adj. Soft Start Features 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 30mΩ N-channel High-Side MOSFET and 12mΩ Low-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 Excellent line and load transient responses 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 30mΩ at VCC=5V N-Channel MOSFET requirements.
