GENERAL DESCRIPTION

The patent-pending ACT8780 is a complete, cost effective, highly-efficient ActivePMUTM power man agement solution that is ideal for a wide range of portable handheld equipment. This device integrates three step-down DC/DC converters and three low dropout linear regulators (LDOs) into a single, thin, space-saving package. An I2C Serial Interface provides programmability for the DC/DC converters and LDOs.
