APW8713A

APW8713A High Input Voltage 8A PWM Converter With Adj. Soft Start Features General Description Adjustable Output Voltage from +0.8V to +12V The APW8713A is a 8A, synchronous, step-down con- - 0.8V Reference Voltage verter with integrated 30mΩ N-channel High-Side - +1% Accuracy over Temperature MOSFET and 9mΩ Low-Side MOSFET. The APW8713A 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 5. The APW8713A provides excellent transient response and 3V Output Power-On-Reset Monitoring on LDO pin Excellent line and load transient responses accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the APW8713A provides very high efficiency over light to heavy loads with loadingmodulated switching frequencies. In PWM Mode, the con- PFM mode for increased light load efficiency verter works nearly at constant frequency for low-noise Programmable PWM Frequency from 100kHz to requirements. 1000kHz The APW8713A is equipped with accurate current-limit, Integrated 30mΩ at LDO=5V N-Channel MOSFET output under-voltage, and output over-voltage protections, For High Side perfect for various applications. A Power-On-Reset func- Integrated 9mΩ at LDO=5V N-Channel MOSFET For tion monitors the voltage on VLDO to prevent wrong Low Side operation during power-on. The APW8713A has exte...
