Overview
ACT8342 Rev0, 26-May-08 Three Channel Integrated Power Management IC for Handheld Portable Equipment FEATURES • Multiple Patents Pending • Three Integrated Regulators − 350mA PWM Step-Down DC/DC − 80mA Low Noise LDO − 150mA Low Noise LDO GENERAL DESCRIPTION The patent-pending ACT8342 is a complete, cost effective, highly-efficient ActivePMUTM 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 ActivePMU 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 350mA output current.
REG1’s output is available in a variety of factory-preset output v...
