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
reconfigured via I
2
C 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, 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
2
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
2
C interface.
The ACT88430 PMIC is available in a 5 x 5 mm 40 pin
QFN package.
