GENERAL DESCRIPTION
The ACT8870 PMIC is an integrated ActivePMU power
management unit. It is designed to power a wide range
of processors, including Atmel’s SAMA5D2, FPGA’s,
peripherals, microcontrollers, and solid-state drive
applications. 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.
ACT8870 is programmed at the factory with default
configuration. These settings can be optimized for a
specific design through the I2C interface. The ACT8870
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 I2C interface.
The ACT8870 PMIC is available in a 5 x 5 mm 40 pin
QFN package or a 3.2 x 4.2 mm 0.5mm 48 ball wafer
chip-scale package.
