The APW7138 is a single-phase, constant-on-time, and synchronous PWM controller which drives N-channel MOSFETs. The APW7138 steps down high voltage of a battery to generate low-voltage chipset or RAM supplies in notebook computers.

The APW7138 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Modulation (PFM) Mode, the APW7138 provides very high efficiency over light load with loadingmodulated switching frequencies. When the inductor current is continuous, the operation automatically enters PWM mode with relatively constant switching frequency. For QFN4x4-16A and TQFN3x3-16 packages, the ForcedPWM Mode works nearly at constant frequency for lownoise requirements.

The APW7138 is equipped with accurate over-current, output under-voltage, and over-voltage protections perfect for NB application. A Power-On-Reset function monitors the voltage on VCC pin to prevent errorneous operation during power-on. The APW7138 has a digital softstart and soft-stop. The internal integrated soft-start ramps up the output voltage with controlled slew rate to reduce the start-up current. The digital soft-stop function actively discharges the output capacitors with controlled reverse inductor current.
