ACT8332 Product Brief, 18-Dec-07 Advanced Information–All Information Subject to Change Three-Channel Integrated Power Management IC for Handheld Portable Equipment FEATURES GENERAL DESCRIPTION • Multiple Patents Pending The patent-pending ACT8332 is a complete, costefficient ActivePMUTM power management solution that is ideal for a wide range of portable handheld equipment. This device integrates a PWM stepdown DC/DC converter and two low-noise, lowdropout linear regulators (LDOs) into 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 ActivePMUTM technology but does not require a high level of integration. • Three Integrated Regulators − 350mA PWM Step-Down DC/DC − 360mA Low Noise LDO − 360mA Low Noise LDO • Independent Enable/Disable Control • Minimal External Components • 3x3mm, Thin-DFN (TDFN33-10) Package − Only 0.75mm Height − RoHS Compliant 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. REG1’s output is available in a variety of factory-preset output voltage, and an adjustable output voltage mode is also available. REG2 and REG3 are low noise LDOs that are available in a variety of fixed output voltage options and are each capable of supplying up to 360mA. APPLICATIONS • Portable Devices and PDAs • MP3/MP4 Players • Wireless Handhelds The ACT8332 is available in a tiny 3mm x 3mm 10-pin Thin-DFN package that is just 0.75mm thin. • GPS Receivers SYSTEM BLOCK DIAGRAM Innovative Products.
