GENERAL DESCRIPTI O N

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

reconfigured via I

C for multiple applications without the

need for PCB changes. The low external component

count and high conf igurabi lity signific antly speeds time

to market. Examples of configurable options include

output voltage, startup time, slew rate, system level

sequencing, switching frequency, sleep modes, operat-

ing modes etc. ACT88430 is programmed at the factory

with default configuration. These settings can be

optimized for a specific design through the I

C interface.

The ACT88430 co mes in several def ault co nfigurat ion.

Contact the factory for specific default configurations.

The core of the dev ice includes four D C/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 P MIC is av ailable 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 optimized for many different pro-

cessors including, but not limited to the following. The

ACT88430 has CMI variations specifically designed to

power the following.
