RAA230407GNP#HA0

Overview

The RAA230407GNP#HA0 is a quad-output power management integrated circuit manufactured by Renesas Electronics Corporation. It integrates three synchronous buck converters and one low-dropout linear regulator within a single package. The device operates with an input voltage range of 2.5V to 5.5V and supports switching frequencies between 1.3MHz and 2.2MHz. Output configurations include adjustable voltages from 0.9V to 4.95V, with current ratings of 500mA, 100mA, and 1.5A for the respective outputs. It is housed in a 32-VQFN (5x5) surface-mount package and functions reliably across a temperature range of -40°C to 85°C.

Feature Summary

• Integrates three synchronous step-down converters and one LDO for multi-rail power distribution
• Supports wide input voltage range suitable for various system power architectures
• Utilizes high-frequency switching operation to minimize external passive component size
• Designed for robust performance across extended industrial temperature ranges

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Industrial control systems needing compact power management solutions
• Embedded computing platforms with mixed analog and digital load requirements
• Automotive infotainment or telematics units operating within specified thermal limits

Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Confirm pin compatibility and thermal characteristics against target PCB layout. Review latest datasheet revisions for any parameter updates. Ensure supply chain sources provide valid traceability documentation. Validate that replacement strategies account for end-of-life constraints.

Selection Notes

Evaluate output current demands against the specific 500mA, 100mA, and 1.5A capabilities of each channel. Consider thermal dissipation requirements given the small 32-VQFN footprint. Assess whether the fixed switching frequency range aligns with electromagnetic interference constraints. Verify input voltage stability matches the 2.5V to 5.5V operational window.

Part Context

This component belongs to the RAA23040x family of quad-output regulators from Renesas. It shares architectural similarities with models like RAA230409GNP#HA0 but differs in specific output current ratings and internal configuration. The series targets applications requiring space-efficient power delivery with integrated regulation capabilities.

Replacement Considerations

Public confirmed substitute part numbers are not available. The manufacturer has declared this component obsolete. Designers must evaluate alternative PMICs with similar topology and output specifications.
