DC DC Switching Controllers datasheet and documents for TPS53624RHAR
DC DC Switching Controllers Overview
The TPS53624RHAR is a dual-phase D-CAP+ buck controller designed for Intel VR12 and VR12.5 compliant CPU core voltage regulation. It features an integrated non-volatile memory (NVM) to minimize external components and supports PMBus telemetry. The device operates with a switching frequency of 500 kHz, delivering up to 50 A output current at a nominal voltage of 1.7 V. It functions within a temperature range of -40°C to +125°C and utilizes a 40-pin VQFN package.
DC DC Switching Controllers Feature Summary
- D-CAP+ architecture with undershoot reduction for fast transient response
- Integrated NVM for programmable parameters and low external component count
- PMBus interface for system telemetry and configuration
- Dynamic phase shedding for efficiency optimization across loads
DC DC Switching Controllers Applications
- Intel VR12 compliant server processor power delivery
- Intel VR12.5 compliant processor power delivery
- High-density CPU core voltage regulation modules
DC DC Switching Controllers Procurement Notes
Verify the suffix RHAR against official Texas Instruments documentation to confirm the specific reel packaging quantity and tape-and-reel specifications. Ensure the order matches the exact part number variant required for your PCB footprint and thermal design. Cross-reference the datasheet revision history for any recent updates to electrical characteristics or recommended operating conditions before finalizing procurement.
DC DC Switching Controllers Selection Notes
Select this controller when designing for Intel VR12 or VR12.5 standards requiring dual-phase capability. It is suitable for applications needing integrated NVM to reduce bill-of-materials complexity. Consider its 500 kHz switching frequency and 50 A current capacity relative to the target load profile and thermal constraints of the VQFN-40 package.
DC DC Switching Controllers Part Context
