General Description

The APW8715E is a 6A, synchronous, step-down converter with integrated 30mW N-channel High-Side

MOSFET and 12mW Low-Side MOSFET. The APW8715E

steps down high voltage to generate low-voltage chipset

or RAM supplies in notebook computers.

TheAPW8715E provides excellent transient response and

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 loadingmodulated switching frequencies. In PWM Mode, the converter works nearly at constant frequency for low-noise

requirements.

The APW8715E 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 APW8715E 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 APW8715E is available in TQFN4x4-23 (Power PAK).
