Overview
The RAA228218GNP#AA0 is a digital dual-output, 20-phase PWM controller from Renesas Electronics. It supports flexible phase allocation across two outputs with a maximum of 20 phases total. The device operates at switching frequencies up to 2MHz and features an AVSBus interface for processor voltage control. It utilizes advanced linear digital modulation and includes zero-delay synthetic current control for high-frequency current balancing.
Feature Summary
- Supports flexible phase distribution between two outputs totaling up to 20 phases
- Integrates AVSBus interface for dynamic processor voltage regulation
- Employs zero-delay synthetic current control for precise current balancing
Applications
- High-density multi-phase DC-DC power conversion systems
- Processor core voltage regulation requiring adaptive voltage scaling
- Server and storage infrastructure power supplies
Procurement Notes
Verify the specific suffix against official Renesas documentation to confirm package and temperature grade variations. Ensure compatibility with PowerNavigator configuration tools. Confirm RoHS3 compliance status through the manufacturer's latest product change notices before finalizing procurement specifications.
Selection Notes
Select this component when designing systems requiring dual independent outputs with shared phase resources. Evaluate the need for AVSBus communication versus standard PMBus protocols. Consider the 2MHz switching frequency capability for minimizing passive component size in space-constrained applications.
Part Context
This part belongs to the RAA228218 series of digital power controllers. It shares architectural similarities with the RAA228228 but may differ in specific pinout or feature enablement. It is designed for integration with Renesas Smart Power Stages to form complete synchronous buck converter solutions.
Replacement Considerations
RAA228228GNP#AA0 is a parameter-equivalent alternative within the same family. Verify software configuration compatibility and pin-to-pin correspondence before substitution.
