描述 Description

The ACT88329 PMIC is an integrated ActiveCiPS? 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 ACT88329 is optimized for SSD ,FPGA and LPDDR5 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 as low as 0.5V, 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.
