ACT88430QJ101-T

Overview

The ACT88430QJ101-T is a specialized Power Management IC (PMIC) designed for microcontrollers and solid-state drives. It integrates four DC-DC buck converters and three low-dropout linear regulators (LDOs). The primary buck channel supports up to 4A, while the secondary channels provide 2.5A each. The LDO configuration includes one 800mA output and two 200mA outputs. Operating with an input voltage range of 2.7V to 5.5V, it features a high switching frequency of 2.25MHz. Output voltages are adjustable from 0.6V to 4V via I2C interface.

Feature Summary

• Integrates four synchronous buck converters and three LDOs for comprehensive power distribution
• Features BUCK1 bypass mode for direct 3.3V system compliance without efficiency loss
• Enables software-defined configuration of timing, slew rates, and voltages via I2C
• Includes multi-level thermal management and serialization protection mechanisms

Applications

• Solid-State Drives (SSD)
• Video Processors
• Microcontrollers
• FPGA Systems

Procurement Notes
