RAA2124224GNP#MA0

Overview

The RAA2124224GNP#MA0 is a PMIC combining a switching regulator and a linear LDO. It features a wide input voltage range of 3V to 40V for the buck converter, which delivers up to 1.1A output current with an adjustable voltage from 0.5V to 5.5V. The integrated LDO provides up to 500mA with an adjustable output from 0.8V to 5.5V. Operating frequencies range from 300kHz to 2MHz. It is housed in a 22-TDFN (3x6) package with an exposed pad and supports temperatures from -40°C to 125°C.

Feature Summary

Integrates a high-current synchronous buck converter and a low-dropout linear regulator within a single compact package.
Supports a wide input voltage range suitable for diverse power supply architectures.
Features programmable switching frequency to optimize external component size and efficiency.
Includes internal sequencing logic to manage startup and shutdown transitions between outputs.

Applications

Portable consumer electronics requiring efficient multi-rail power distribution
IoT devices with mixed analog and digital load requirements
Industrial control modules operating in extended temperature environments

Procurement Notes

Verify the specific suffix code carefully during procurement. The #MA0 designation indicates tape and reel packaging. Confirm that this exact part number matches your bill of materials, as suffix variations often denote different packaging formats or minor revisions rather than functional changes. Ensure compatibility with your assembly process regarding moisture sensitivity levels.

Selection Notes

Select this component when a combined solution for high-current switching regulation and clean linear regulation is required in a space-constrained design. Evaluate the thermal performance of the 22-TDFN package against your system's heat dissipation capabilities. Consider the adjustable frequency range to balance electromagnetic interference constraints with passive component footprint requirements.

Part Context

This device belongs to the RAA21242xx series of power management ICs from Renesas Electronics. These components are designed to provide integrated power solutions for applications needing both efficient DC-DC conversion and precise linear regulation. The series targets markets demanding high integration and reduced board space.
