General Description

The APW7108 is a dual-channel, constant on-time, and synchronous PWM controller which drives dual Nchannel MOSFETs for each channel.

The APW7108 steps down high voltage of a battery to generate low-voltage chipset or RAM supplies in notebook computers.

The APW7108 provides excellent transient response and accurate DC voltage output in either PFM or PWM mode.

Overview

APW7108 Dual Mobile-Friendly PWM Controller.

Key Features

  • Adjustable Output Voltage up to 5.5V - 0.9V Reference Voltage - ±1% Accuracy Over Temperature.
  • Operates from an Input Battery Voltage Range of 5V to 24V or from 3.3V/5V System Rail.
  • Power-On-Reset Monitoring on VCC Pin.
  • Selectable Forced PWM or Automatic PFM/PWM Mode.
  • Constant-On-Time Control Scheme - Switching Frequency Compensation for PWM Mode - Constant Switching Frequency (CH1: 345kHz, CH2: 255KHz) in PWM Mode with DC Output Current.
  • Ex.
