RAA230409GNP#HA0

Overview

The RAA230409GNP#HA0 is a quad-output power management IC from Renesas, integrating three synchronous buck converters and one low-dropout regulator. It operates within an input voltage range of 2.5V to 5.5V and supports switching frequencies between 1.3MHz and 2.2MHz. The device provides four distinct output channels: Output 1 delivers up to 500mA with adjustable voltage from 0.9V to 4.95V; Output 2 supplies 100mA in the same voltage range; Output 3 offers 1.5A capability; and Output 4 functions as a linear regulator. Packaged in a compact 32-VQFN (5x5) surface-mount format, it is designed for applications requiring multiple regulated rails from a single supply.

Feature Summary

• Integrates three synchronous step-down converters and one LDO for efficient multi-rail power generation
• Supports flexible switching frequency adjustment between 1.3MHz and 2.2MHz to optimize external component size
• Provides independent current capabilities across outputs, including a high-current 1.5A channel

Applications

• Portable electronic devices requiring multiple voltage domains
• Embedded systems utilizing mixed-signal architectures
• Industrial control modules needing isolated or separate power rails

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Cross-reference datasheet revisions to ensure compatibility with existing designs, noting that labeling updates may occur without functional changes.

Selection Notes

Select this component when designing systems requiring four distinct regulated voltages from a single input source. Evaluate thermal performance carefully, particularly for the 1.5A output channel, as heat dissipation depends on load conditions and PCB layout. Ensure input voltage stability remains within the specified 2.5V to 5.5V range for reliable operation.

Part Context

This part belongs to the RAA23040x series of quad-output PMICs from Renesas. It shares architectural similarities with other members like the RAA230402GFT#BA0 but differs in packaging and specific output configurations. The series targets compact power solutions for portable and embedded electronics.
