RAA228228R0VGNP#HA0

Overview

The RAA228228R0VGNP#HA0 is a digital dual-output, 20-phase PWM controller from Renesas Electronics. It features an integrated adaptive voltage regulation bus (AVSBus) interface for processor communication. The device supports flexible phase allocation across two outputs with a maximum switching frequency of 2 MHz. It utilizes zero-delay synthetic current control and advanced linear digital modulation to optimize efficiency and transient response. The controller includes non-volatile memory for configuration storage and comprehensive fault management capabilities.

Feature Summary

Digital dual-output architecture supporting up to 20 total phases with flexible distribution
Zero-delay synthetic current control for precise high-frequency current balancing
Integrated AVSBus interface enabling direct communication with processors for adaptive voltage scaling
Advanced linear digital modulation with automatic phase addition/removal for optimized load efficiency

Applications

Artificial intelligence and accelerator cards including FPGA and ASIC power supplies
Server and storage equipment load point regulators
Network equipment and telecom/datacom infrastructure power systems

Procurement Notes

Verify the specific suffix 'R0V' against official Renesas documentation to confirm exact marking and revision status. Ensure compatibility with required SMBus/PMBus versions and AVSBus implementations. Confirm package integrity for the 68-lead QFN form factor prior to assembly. Cross-reference design-in requirements with supported smart power stage devices.

Selection Notes

Select this component for designs requiring high-density power conversion with dynamic voltage scaling needs. The dual-output capability allows independent phase allocation for multi-rail architectures. Consider the 2 MHz switching frequency for reduced passive component size. Evaluate the need for AVSBus integration versus standard PMBus monitoring based on system complexity.

Part Context

This part belongs to the RAA2282x series of digital multiphase controllers. It represents a second-generation platform offering enhanced scalability without phase multipliers. The series focuses on eliminating the need for external phase doublers while maintaining high performance through proprietary digital control algorithms and integrated non-volatile memory.
