APW8713 High Input Voltage 8A PWM Converter With Adj. Soft Start Features • Adjustable Output Voltage from +0.8V to +12V - 0.8V Reference Voltage - +1% Accuracy over Temperature General Description The APW8713 is a 8A, synchronous, step-down converter with integrated 30mΩ N-channel High-Side MOSFET and 9mΩ Low-Side MOSFET. The APW8713 steps down high voltage to generate low-voltage chipset or RAM supplies in notebook computers. The APW8713 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the APW8713 provides very high efficiency over light to heavy loads with loadingmodulated switching frequencies. In PWM Mode, the converter works nearly at constant frequency for low-noise requirements. The APW8713 is equipped with accurate current-limit, output under-voltage, and output over-voltage protections, perfect for various applications. A Power-On-Reset function monitors the voltage on VCC to prevent wrong operation during power-on. The APW8713 has external adjustable soft-start and built-in an integrated output discharge method for soft stop. A soft-start ramps up the output voltage with programmable timing to reduce the start-up current. A soft-stop function actively discharges the output capacitors. The APW8713 is available in TQFN4x4-23 (Power PAK). • • • • • • • • • • • • • • • • • Operates from An Input Battery Voltage Range of +2.7V to +28V Power-On-Reset Monitoring on VCC pin Excellent line and load transient responses PFM mode for increased light load efficiency Programmable PWM Frequency from 100kHz to 1000kHz Integrated 30mΩ at VCC=5V N-Channel MOSFET For High Side Integrated 9mΩ at VCC=5V N-Channel MOSFET For Low Side Integrated Bootstrap Forward P-CH MOSFET External Adjustable Soft-Start and Soft-Stop Selectable Forced PWM or automatic PFM/PWM mode Power Good Monitoring 70% Under-Voltage Protection 125% Over-Voltage Protection Current-Limit Protection - Using Sense Low-Side MOSFET’ s RDS(ON) Over-Temperature Protection TQFN-23 4mmx4mm package Lead Free and Green Device Available (RoHS Compliant) Applications • • • • • • • Notebook Mother Board Table PC Hand-Held Portable AIO PC Set-top boxes LCD TV ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders.
