GENERAL DESCRIPTION

The ACT88430 PMIC is an integrated ActivePMU

power management unit . It is designed to power a wid e

range of processors, including video processors,

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

drive applications. It is highly flexible and can be

reconfigured via I

C for multiple appli cations without the

need for PCB changes. The low external component

count and high configurability significantly speeds time

to market. Examples of configurable options include

output voltage, startup time, slew rate, system level

sequencing, swit ching freq uency, sl eep mode s, ope rat -

ing modes etc. ACT88430 is programme d at the factory

with default configuration. These settings can be

optimized for a spe cific design through the I

C interface.

The ACT88430 comes in several default configuration.

Contact the factory f or 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 r equire small ceramic c apacitors. All are

highly configurable via the I

C interface.

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

QFN package or in a 4.17 x 3.17 mm 48-ball WLCSP

package.

The ACT88430 can be opti mized for many different pro-

cessors including, but not limited to the following.
