RAA230409GFT#BA0

Overview

The RAA230409GFT#BA0 is a synchronous switching regulator and linear voltage regulator integrated circuit manufactured by Renesas Electronics. It features four output channels configured as three synchronous buck converters and one low-dropout (LDO) regulator. The device operates within an input voltage range of 2.5V to 5.5V and supports switching frequencies between 1.3MHz and 2.2MHz. It is housed in a 32-TQFP package with dimensions of 7x7mm.

Feature Summary

• Integrates three synchronous buck converters and one LDO regulator for combined power management
• Supports adjustable output voltages ranging from 0.9V to 4.95V across multiple channels
• Operates at high switching frequencies up to 2.2MHz to optimize passive component size

Applications

• Portable electronic devices requiring multi-rail power distribution
• Embedded systems utilizing mixed-signal power architectures
• Industrial control modules needing compact PMIC solutions

Procurement Notes

Verify the specific suffix #BA0 against official Renesas documentation to confirm exact electrical characteristics and packaging details. Confirm current availability status, as this part may be subject to limited supply or end-of-life restrictions. Ensure compatibility with existing board layouts regarding the 32-TQFP footprint and thermal requirements before procurement.

Selection Notes

Select this component when a single IC solution is required to provide both high-efficiency switching regulation and precise linear regulation. The integration of three buck converters and one LDO reduces bill of materials count and board space. Verify that the required output currents align with the specific channel capabilities defined in the datasheet.
