UCC28250PW

DC DC Switching Controllers Overview

The UCC28250PW is an advanced PWM controller manufactured by Texas Instruments, designed for high-performance power conversion applications. It operates within a supply voltage range of 4.7 V to 17 V and supports switching frequencies up to 1 MHz. The device features four output channels with a maximum duty cycle of 100% and provides an output current capability of 200 mA. It is housed in a 20-pin TSSOP package and functions reliably across an extended temperature range from -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Supports multiple converter topologies including full bridge, half bridge, and push-pull configurations
• Enables pre-bias operation to allow safe startup under existing load conditions
• Provides precise control through integrated soft-start and frequency synchronization capabilities

DC DC Switching Controllers Applications

• High-density server power supplies
• Telecommunications power systems
• Industrial motor drives

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-20 package variant when sourcing. Ensure compatibility with the required operating temperature range and input voltage specifications for the target design. Cross-reference the manufacturer datasheet for pinout accuracy and thermal management requirements during integration.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring multi-topology flexibility and pre-bias functionality. Consider the TSSOP-20 package constraints regarding thermal dissipation and PCB layout space. Evaluate the 200 mA output drive strength against gate charge requirements of the external power switches to ensure adequate performance at the target switching frequency.

DC DC Switching Controllers Part Context

This part belongs to the UCC28250 family of advanced PWM controllers from Texas Instruments. It shares core architectural features with other variants in the series but differs in packaging and specific electrical characteristics. The family is engineered for efficient power management in demanding industrial and commercial environments.

DC DC Switching Controllers Replacement Considerations

The UCC28250RGPR offers equivalent functionality in a QFN-20 package. Verify pin-to-pin compatibility and thermal performance differences before substitution.
