General Description
The APW8716 is a 12A, synchronous, step-down converter with integrated 9.7mW N-channel High-Side
MOSFET and 5.2mW Low-Side MOSFET. The APW8716
steps down high voltage to generate low-voltage chipset
or RAM supplies in notebook computers.
The APW8716 provides excellent transient response and
accurate DC voltage output in either PFM or PWM Mode.
In Pulse Frequency Mode (PFM), the APW8716 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 APW8716 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 APW8716 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 APW8716 is available in TQFN5x5-30 (Power PAK).
