Overview
The RAA228228R0VGNP#HA1 is a digital dual-output, 20-phase PWM controller from Renesas Electronics Corporation. It features an Adaptive Voltage Scaling Bus (AVSBus) interface for high-speed communication between the controller and load. The device supports flexible phase configurations where the sum of phases on both outputs does not exceed 20. It operates with a switching frequency of 2 MHz and utilizes a 68-VFQFN exposed pad package.
Feature Summary
- Digital control architecture supporting dual independent voltage rails
- AVSBus interface enabling high-speed bidirectional communication for dynamic voltage scaling
- Flexible phase allocation allowing up to 20 total phases across two outputs
- Integrated synchronous buck controller topology
Applications
- High-performance processor core power delivery
- Server and data center CPU voltage regulation modules
- Industrial systems requiring precise dynamic voltage adjustment
- Telecommunications base station power management
Procurement Notes
Verify the specific suffix HA1 against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering part number matches the required tape-and-reel packaging configuration. Cross-reference the RoHS status and moisture sensitivity level with your assembly process requirements before finalizing procurement orders.
Selection Notes
Select this component when high-speed AVSBus communication is required alongside standard PMBus support. It is suitable for applications needing simultaneous regulation of two distinct voltage domains with a combined phase count up to twenty. Consider the 68-QFN package constraints for thermal dissipation and PCB layout space during the design phase.
Part Context
This IC belongs to the RAA228228 family of digital power controllers designed for demanding computing loads. The series emphasizes energy efficiency through adaptive voltage scaling. The RAA228228R0VGNP#HA1 variant specifically denotes the commercial grade version with the HA1 suffix indicating specific packaging or testing attributes defined by Renesas.
Replacement Considerations
Direct substitutes include other models within the RAA228228 family such as RAA228228GNP#AA0 or RAA228228GNP#MA0. Verify that alternative suffixes match the required package type and operational temperature range. Functional equivalence requires confirming identical phase limits and interface protocols.
