RAA2124214GNP#MA0

Overview

The RAA2124214GNP#MA0 is a mixed-signal PMIC integrating one switching buck converter and one low-dropout linear regulator. It operates with input voltages of 1.8V to 6V for the LDO and 3V to 40V for the buck. The buck output provides 0.5V to 5.5V at 1.1A, while the LDO delivers 0.8V to 5.5V at 500mA. Switching frequency ranges from 300kHz to 2MHz. The device features an integrated sequencer and is housed in a 22-WFDFN package with exposed pad.

Feature Summary

Integrates a high-current synchronous buck converter and a precision LDO in a single compact package.
Includes an internal power-on reset and sequencing controller for reliable multi-rail system startup.
Supports wide input voltage range up to 40V for the switching section to accommodate various bus architectures.

Applications

Portable electronic devices requiring efficient multi-voltage rail generation
Industrial control systems needing robust power management under varying input conditions
IoT gateways and edge computing nodes with mixed analog and digital load requirements

Procurement Notes

This component is officially listed as obsolete by Renesas Electronics Corporation. Designers must verify current availability through authorized distributors or consider alternative sourcing channels. Procurement should focus on remaining stock levels rather than new production runs. Ensure all ordering documents reference the complete part number including the suffix to guarantee correct package and tape-reel specifications.

Selection Notes

Select this IC when a combined solution for high-efficiency step-down conversion and clean linear regulation is required within a limited board area. The integrated sequencer simplifies design complexity compared to discrete solutions. Verify that the thermal performance of the 22-TDFN package meets the application's heat dissipation needs under maximum load conditions.

Part Context

The RAA212421 series represents Renesas' portfolio of highly integrated power management units designed for space-constrained applications. This specific model combines switching and linear technologies to optimize efficiency and noise performance. It belongs to a family of PMICs aimed at reducing component count and assembly costs in modern electronic systems.
