GENERAL DESCRIPTION

The patent-pending ACT8332 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 inte-

grates 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 voltage options,

and an adjustable output voltage mode is also avail-

able. REG2, REG3 are low noise, high PSRR linear

regulators that are capable of supplying up to

360mA, and 360mA, respectively.

The ACT8332 is available in a tiny 3mm

× 3mm

10-pin Thin-DFN package that is just 0.75mm thin.
