APW8715E

APW8715E High Input Voltage 6A PWM Converter With Low Iq Features General Description Adjustable Output Voltage from +0.8V to +12V - 0.8V Reference Voltage - +1% Accuracy over Temperature The APW8715E is a 6A, synchronous, step-down converter with integrated 30mΩ N-channel High-Side MOSFET and 12mΩ Low-Side MOSFET. The APW8715E 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 APW8715E provides excellent transient response and Excellent line and load transient responses PFM mode for increased light load efficiency accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the APW8715E 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. For High Side The APW8715E is equipped with accurate current-limit, Integrated 12mΩ at VCC=5V N-Channel MOSFET output under-voltage, and output over-voltage protections, For Low Side perfect for various applications.
