General Description
The APW8713C is a 10A, synchronous, step-down converter with integrated 30mΩ N-channel High-Side MOSFET and 9mΩ Low-Side MOSFET. The APW8713C steps down high voltage to generate low-voltage chipset or RAM supplies in notebook computers. The APW8713C provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the APW8713C 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 lownoise requirements. The APW8713C 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 APW8713C 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 APW8713C is available in TQFN4x4-23 (Power PAK).
