GENERAL DESCRIPTION

The ACT88321 PMIC is an integrated ActiveCiPSTM

power management integrated circuit. It powers a wide

range of processors, including solid-state drive applica-

tions, video processors, FPGA’s, wearables, periph-

erals, and microcontrollers. The ACT88321 is optimized

for SSD and FPGA applications. A similar product,

ACT88328, is optimized for video and wearables appli-

cations. The ACT88321 is highly flexible and can be re-

configured 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 se-

quencing, switching frequency, sleep modes, operating

modes etc. ACT88321 is programmed at the factory

with a default configuration. These settings can be opti-

mized for a specific design through the I2C interface.

The ACT88321 is available in several default configura-

tion. Contact the factory for specific default configura-

tions.

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

converters using integrated power FETs, two low-drop-

out regulators (LDOs). Buck1 and LDO1 can be config-

ured as a load switch. Buck1 is a peak current mode,

fixed frequency DC-DC step down converter that is op-

timized for output voltage closes to the input voltage.

Buck1 switches at either 1.125MHz or 2.25MHz, requir-

ing only three small components for operation. Buck2

and Buck3 use an asynchronous constant on-time,

ACOT, control architecture to optimize the load transi-

ent response with smaller output capacitors. The LDOs

only require small ceramic capacitors. All outputs are

highly configurable via the I2C interface.

The ACT88321 PMIC is available in a 2.18 x 2.58 mm

30 ball WLCSP package.
