Datasheet/Datenblatt


High Input Voltage 8A PWM Converter With Adj. Soft Start


General Description

The APW8713A is a 8A, synchronous, step-down converter with integrated 30mW N-channel High-Side MOSFET and 9mW Low-Side MOSFET. The APW8713A steps down high voltage to generate low-voltage chipset or RAM supplies in notebook computers.
The APW8713A provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), theAPW8713A provides very high efficiency over light to heavy loads with loading modulated switching frequencies. In PWM Mode, the converter works nearly at constant frequency for low-noise requirements.
The APW8713A 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 VLDO to prevent wrong operation during power-on. The APW8713A 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 APW8713A is available in TQFN4x4-23 (Power PAK).
