TPS51620RHAT

Special Purpose Regulators Overview

The TPS51620RHAT is a dual-phase D-CAP+ mode step-down controller designed for IMVP6+ CPU and GPU Vcore applications. It operates within an input voltage range of 4.5V to 17V, delivering up to 6A output current. The device features integrated high-side and low-side MOSFETs in a compact 3.5mm x 3.5mm VQFN-14 package. Key electrical parameters include a switching frequency range of 480kHz, an output voltage adjustment from 0.8V to 15V, and operation across a temperature range of -40°C to +150°C.

Special Purpose Regulators Feature Summary

• Integrates synchronous buck converter with built-in power FETs for space optimization
• Utilizes D-CAP+ control topology for fast transient response without external compensation
• Supports programmable slow start and power sequencing via SS/TR pin
• Includes comprehensive protection mechanisms such as thermal shutdown and current limiting

Special Purpose Regulators Applications

• Central processing unit (CPU) core voltage regulation
• Graphics processing unit (GPU) power delivery
• Point-of-load conversion in communication networks
• General-purpose power management systems requiring high efficiency

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'RHAT' against official Texas Instruments documentation to confirm tape-and-reel packaging and moisture sensitivity level. Ensure compatibility with IMVP6+ specifications if used for processor cores. Cross-reference the exact part number with the manufacturer's current product status to avoid obsolete components.

Special Purpose Regulators Selection Notes

Select this component when a compact solution with integrated power stages is required for high-current applications. The D-CAP+ architecture simplifies design by eliminating external error amplifier compensation. Consider the operating temperature range and package thermal performance for high-density PCB layouts.

Special Purpose Regulators Part Context

This device belongs to the TPS54620 family of SWIFT converters. It shares similar architectural features with other members of the series but is specifically optimized for dual-phase operation in high-performance computing environments. The integration of power switches distinguishes it from discrete controller solutions.

Special Purpose Regulators Replacement Considerations

Direct substitutes may include TPS54620 variants or other IMVP6+ compatible controllers from Texas Instruments. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
