GENERAL DESCRIPTION

The ACT88430 PMIC is an integrated ActivePMU

power management unit. It is designed to power a wide

range of processors, including video processors,

FPGA’s, peripherals, microcontrollers, and solid-state

drive applications. It is highly flexible and can be recon-

figured via I

C for multiple applications without the need

for PCB changes. The low external component count

and high configurability significantly speeds time to mar-

ket. Examples of configurable options include output

voltage, startup time, slew rate, system level sequenc-

ing, switching frequency, sleep modes, operating

modes etc. ACT88430 is programmed at the factory

with default configuration. These settings can be opti-

mized for a specific design through the I

C interface.

The ACT88430 comes in several default configuration.

Contact the factory for specific default configurations.

The core of the device includes four DC/DC step down

converters using integrated power FETs, three low-

dropout regulators (LDOs), and an optional load switch.

Each DC/DC regulator switches at 2.25MHz, requiring

only three small components for operation. The LDOs

only require small ceramic capacitors. All are highly

configurable via the I

C interface.

The ACT88430 PMIC is available in a 5 x 5 mm 40 pin

QFN package.
