RAA228227GNP#HA0

Overview

The RAA228227GNP#HA0 is a digital dual-output, 16-phase PWM controller from Renesas Electronics. It features a 60-lead 7x7 mm QFN package and operates at a switching frequency of 2 MHz. The device supports up to two outputs with a maximum of 16 phases combined (X+Y ≤ 16). It includes an AVSBus interface for adaptive voltage regulation and SMBus/PMBus V1.3 compatibility. Input voltage ranges from 4.5 V to 18 V, with output voltages up to 3.05 V.

Feature Summary

Digital dual-output architecture supporting flexible phase allocation across two rails
AVSBus interface enables high-speed communication for adaptive voltage scaling
Advanced linear digital modulation provides optimized transient response and efficiency
Integrated black box fault logging with first-fault indication for system diagnostics

Applications

DDR memory power solutions
Artificial intelligence and accelerator cards
Network equipment power supplies
Server and storage systems

Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure that the ordering part number matches the required lead frame and moisture sensitivity level. Cross-reference the datasheet revision history to confirm component availability and any recent manufacturing changes before finalizing procurement orders.

Selection Notes

Select this controller for designs requiring high-density power delivery with precise digital control. The 16-phase capability suits applications needing balanced current sharing without excessive component count. Consider the 2 MHz switching frequency for smaller passive sizes. Validate thermal performance within the 7x7 QFN footprint against the target load requirements.

Part Context

This component belongs to the RAA228227 series of digital power controllers. It complements other models in the family by offering a mid-range phase count between lower-power single-output devices and higher-capacity multi-rail controllers. The series utilizes Renesas' proprietary digital synthesis current control technology for improved stability.
