UCC28250RGPR

DC DC Switching Controllers Overview

The UCC28250RGPR is an advanced PWM controller from Texas Instruments designed for high-performance power conversion. It supports full bridge, half bridge, and push-pull topologies with a switching frequency range of 85kHz to 1.15MHz. The device features a maximum duty cycle of 100% and operates on a supply voltage between 4.7V and 17V. It provides two output channels with a maximum output current of 200mA. The component is housed in a 20-VQFN package with a 4x4mm footprint and functions within a temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Supports pre-bias operation for safe startup into pre-charged outputs
• Enables synchronous rectification control for improved efficiency
• Integrates adjustable soft-start and programmable frequency capabilities

DC DC Switching Controllers Applications

• High-density DC/DC converters
• Isolated power supplies using full bridge or half bridge topologies
• Push-pull converter designs requiring high efficiency

DC DC Switching Controllers Procurement Notes

Verify the specific suffix RGPR indicates the VQFN-20 reel packaging configuration. Confirm RoHS compliance status matches current manufacturing standards. Ensure the design accounts for the thermal performance requirements of the exposed pad QFN package during implementation.

DC DC Switching Controllers Selection Notes

Select this component when designing isolated converters requiring synchronous rectification and pre-bias handling. It is suitable for applications demanding wide input voltage ranges and high switching frequencies up to 1.15MHz. Consider the thermal dissipation characteristics of the QFN package for high-power density designs.

DC DC Switching Controllers Part Context

This part belongs to the UCC28250 family of advanced PWM controllers. It shares functional similarities with other TI switchers but is distinct in its support for synchronous rectification and pre-bias operation. The RGPR variant specifically denotes the tape and reel packaging format for surface-mount assembly.

DC DC Switching Controllers Replacement Considerations

Check for UCC28250RGPT as an alternative packaging option within the same series. Verify compatibility with UC2825A variants if legacy pinouts are required, noting differences in topology support and operating voltage ranges.
