Advanced PMU with 3 Bucks, 2 LDOs and Load Bypass Switch

BENEFITS and FEATURES

GENERAL DESCRIPTION

TheACT88325 PMIC is an integrated ActivePMU power

management unit. It is highly flexible and can be

reconfigured via I²C for multiple applications 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, switching frequency, sleep modes,

operating modes etc. The core of the device includes 3

DC/DC step down converters using integrated power

FETs, and 2 low-dropout regulators (LDOs). Each

regulator can be configured for a wide range of output

voltages through the I²C interface.



Wide input voltage range

Vin = 2.7V to 5.5V

Complete integrated power solution

One 4A DC/DC Step-Down with Bypass

Mode

Two 3A DC/DC Step-Down Regulators

Two 300mA LDOs

High Power Load Switch Gate Driver with

Slew Rate Control



Space Savings

Fully integrated

High Fsw = 2.25MHz or 1.125MHz

Integrated sequencing

ACT88325 is programmed at the factory with a default

configuration. The default settings can be optimized for

a specific design through the I²C interface. Contact the

factory for specific default configurations.

Easy system level design

Configurable sequencing

Seamless sequencing with external supplies

Programmable Reset and Power Good

GPIO’s

The ACT88325 includes features that allow flexibility for

all system level configurations. The buck converter can

be reconfigured as a bypass switch. It also contains a

high power load switch controller. It’s external power

supply enable and power good interface allows

seamless sequencing with external power supplies.



Buck 1 Bypass Mode for 3.3V system level

compliance

Highly configurable

µP interface for status reporting and con-

trollability

The ACT88325 PMIC is available in a 2.7 x 3 mm 36 pin

WLCSP package.

Flexible Sequencing Options

I²C Interface – 1MHz

Multiple Sleep Modes
