RAA2124214GNP#AA0

Overview

The RAA2124214GNP#AA0 is a PMIC combining one switching buck converter and one LDO. It operates with input voltages of 1.8V to 6V for the LDO and 3V to 40V for the buck. The buck output ranges from 0.5V to 5.5V at 1.1A, while the LDO provides 0.8V to 5.5V at 500mA. Switching frequency is adjustable between 300kHz and 2MHz. It features integrated sequencing in a 22-TDFN (3x6) package.

Feature Summary

• Integrates a synchronous buck converter and an LDO within a single component
• Includes internal sequencing logic for controlled power-up and power-down sequences
• Supports wide input voltage range up to 40V for the switching regulator section

Applications

• Portable electronic devices requiring multiple regulated rails
• Embedded systems needing compact mixed-signal power solutions
• Industrial equipment utilizing wide input voltage ranges

Procurement Notes

Verify current availability status as this part number may be discontinued or subject to obsolescence notices. Confirm that the specific suffix matches required packaging and environmental compliance standards. Cross-reference official Renesas documentation for any recent product change notifications affecting lead times or specifications before finalizing procurement plans.

Selection Notes

Select this component when space constraints require integrating both linear and switching regulation. Ensure the application demands the specific current capabilities of 1.1A for the buck and 500mA for the LDO. Verify that the operating temperature range meets system requirements and that the 22-TDFN package fits the PCB layout constraints.
