RAA2124214GNP#HA0

Overview

The RAA2124214GNP#HA0 is a mixed-signal PMIC integrating one synchronous 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 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-WFDFN package.

Feature Summary

• Integrates a high-voltage synchronous buck converter and a low-voltage LDO within a single compact package.
• Includes an internal sequencer to manage power-up and power-down transitions between outputs.
• Supports flexible switching frequencies ranging from 300kHz to 2MHz for optimization of efficiency and component size.

Applications

• Portable electronic devices requiring efficient multi-rail power management
• Industrial control systems utilizing mixed voltage domains
• Automotive infotainment and sensor modules

Procurement Notes

Verify the specific suffix #HA0 against official Renesas documentation to confirm pin compatibility and thermal characteristics. Confirm availability status as previous variants may be obsolete. Ensure ESD handling protocols are followed during assembly due to the exposed pad WDFN package type.

Selection Notes

Select this component when a design requires both wide-input voltage tolerance and precise low-noise regulation. The integrated sequencer simplifies board layout by managing rail dependencies. Verify that the required output currents fit within the 1.1A buck and 500mA LDO limits for the target application environment.

Part Context

This part belongs to the RAA212421 family of hybrid power management ICs. These devices combine switching and linear technologies to address diverse power needs in space-constrained applications. The family typically targets systems needing robust input ranges alongside stable analog supply rails.

Replacement Considerations

RAA2124214GNP#MA0 is a documented alternative within the same product family. Verify functional equivalence and pinout compatibility before substitution.
