GENERAL DESCRIPTION

The patent-pending ACT8796 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 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.

REG1, REG2 and REG3 are fixed-frequency,

current-mode PWM step-down DC/DC converters

that are optimized for high efficiency and are

capable of supplying up to 750mA, 750mA and

550mA, respectively. REG4, REG5 and REG6 are

low noise, high PSRR linear regulators that are

capable of supplying up to 250mA each.

The ACT8796 is available in a tiny 4mm×4mm 24-

pin Thin-QFN package that is just 0.75mm thin.
