- Two Integrated Step-Down DC/DC Converters - REG1: 350mA - REG2: 550mA ACT8325 Rev0, 13-May-08 Dual PWM Step-Down DC/DCs in TDFN33 GENERAL DESCRIPTION The patent-pending ACT8325 integrates two stepdown DC/DCs into a single, thin, space-saving package to provide a cost-effective, highly-efficient ActivePMUTM power management solution. This device is ideal for a wide range of portable handheld equipment that can benefit from the advantages of ActivePMU technology but do not require a high level of integration. REG1 and REG2 are fixed-frequency, current-mode PWM step-down DC/DC converters that are optimized for high efficiency and are capable of supplying up to 350mA and 550mA, respectively. Both outputs are available in a wide range of factorypreset output voltage options, and an adjustable output voltage mode is also available. The ACT8325 is available in a tiny 3mm x 3mm 10-pin Thin-DFN package that is just 0.75mm thin.
