GENERAL DESCRIPTION
The patent-pending ACT8352 is a plete, cost effective, highly-efficient Active PMUTM power management solution that is ideal for a wide range of portable handheld equipment. This device integrates one PWM step-down DC/DC converter and two low noise, low dropout linear regulators (LDOs) in a single, thin, space-saving package. This device is ideal for a wide range of portable handheld equipment that can benefit from the advantages of Active PMU technology but does not require a high level of integration. REG1 is a fixed-frequency, current-mode PWM step-down DC/DC converter that is optimized for high efficiency and is capable of supplying up to 350m A output current. REG1’s output is available in a variety of factory-preset output voltage options, and an adjustable output voltage mode is also available. REG2, REG3, and REG4 are low noise,...
