General Instructions

The ACT8870 PMIC is an integrated ActivePMU power supply

management unit. It is designed to provide a wide range of power

processors, including Atmel's SAMA5D2, FPGA's,

Peripheral, Microcontroller and Solid State Drive applications.

It is highly flexible and can be reconfigured

Multiple applications via I2C without

PCB replacement. low number of external components, 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 mode, operating mode, etc.

The ACT8870 is programmed at the factory with a default configuration.

These settings can be optimized for specific conditions

Design through the I2C interface. ACT8870 is coming

in several default configurations. contact factory

A specific default configuration.

The core of the device consists of four DC/DC bucks

Converters with Integrated Power FETs, Three Low Dropout

voltage regulator (LDO) and optional load switch.

The switching frequency of each DC/DC regulator is 2.25MHz, requiring

Only three widgets are needed to operate. low pressure drop

Only small ceramic capacitors are required. are very high

Configurable via I2C interface.

ACT8870 PMIC provides 5 x 5 mm 40 pins

QFN package or 3.2x4.2 mm 0.5mm 48-ball wafer

Chip scale packaging.
