UCC28251RGPT

DC DC Switching Controllers Overview

The UCC28251RGPT is a DC-DC switching controller IC manufactured by Texas Instruments, housed in a 20-QFN (4x4) surface-mount package. It supports multiple topologies including full bridge, half bridge, and push-pull configurations. The device operates with a supply voltage range of 4.7V to 17V and features a programmable switching frequency from 42kHz to 945kHz. It provides two positive PWM outputs with integrated synchronous rectification control. Key operational parameters include a junction temperature range of -40°C to 125°C.

DC DC Switching Controllers Feature Summary

• Supports advanced multi-topology applications including full bridge, half bridge, and push-pull converters.
• Integrates synchronous rectifier control for enhanced efficiency in power conversion designs.
• Includes comprehensive protection and control features such as current limiting, enable functionality, frequency control, slope compensation, and soft-start capabilities.

DC DC Switching Controllers Applications

• High-efficiency AC-DC power supplies
• DC-DC converter modules
• Server and data center power distribution

DC DC Switching Controllers Procurement Notes

Verify the specific suffix RGPT corresponds to the 20-QFN package variant when sourcing. Confirm RoHS3 compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to the sensitive nature of the CMOS internal circuitry within the exposed pad QFN package.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring flexible topology support and high-frequency operation up to 945kHz. The integrated synchronous rectification driver reduces external component count compared to non-synchronous alternatives. Consider the thermal performance of the 20-QFN package for high-power density applications requiring robust heat dissipation.

DC DC Switching Controllers Part Context

This part belongs to the UCC28251 family of advanced PWM controllers designed for versatile power management solutions. It complements other variants like the UCC28251PWR which utilizes a TSSOP package, offering designers flexibility in PCB layout and assembly methods while maintaining identical electrical performance characteristics across the product line.

DC DC Switching Controllers Replacement Considerations

UCC28251PWR is a pin-compatible alternative available in a 20-TSSOP package. Verify that the target PCB footprint accommodates the TSSOP outline dimensions if substituting the QFN variant for the SOIC-style package.
