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 loading-
modulated switching frequencies. In PWM Mode, the con-
verter 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 func-
tion 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 dis-
charge 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).
