Description

The ACT88327 PMIC is an integrated ActiveCiPSTM power management integrated circuit. It powers a wide range of processors, including solid-state drive appli-cations, video processors, FPGA’s, wearables, pe-ripherals, and microcontrollers. The ACT88327 is opti-mized for SSD and FPGA 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 con-figurable options include output voltage, startup time, slew rate, system level sequencing, switching frequen-cy, sleep modes, operating modes etc. The core of the device includes three DC/DC step down converters using integrated power FETs, two low-dropout regulators (LDOs). Buck1 and LDO1 can be configured as a load switch. Each DC/DC regulator switches at either 1.125MHz or 2.25MHz, requiring only three small components for operation. The LDOs only require small ceramic capacitors. All are highly config-urable via the I2C interface.

Features

  • 2.7V ~ 5.5V Input Voltage Range
  • Buck 1: 4A Buck / Load Switch
  • Buck 2: 4A Buck Optimized for Low Output Voltage
  • Buck 3: 2A Peak Buck
  • All Bucks Work with 0.47uH Inductors
  • LDO1 : 390mA LDO, can be Configured as Load Switch for up to 1A
  • LDO2: 390mA LDO
  • I2C Serial Interface for Monitoring and Control
  • 7 Configurable GPIOs
  • Optimized Heavy/Light Load Efficiency

Typical applications

  • Solid-State Drives (SSD) / FPGA / Computer Vision
  • Portable Audio / Video
