UCC28050D

Overview

The UCC28050D is a transition mode power factor correction (PFC) controller manufactured by Texas Instruments. It operates with a switching frequency of 200 kHz and supports surface-mount installation in an SOIC-8 package. The device functions within a temperature range of -40°C to +85°C. Key electrical specifications include a quiescent supply current of 75 µA, ensuring efficient low-power operation during standby or light-load conditions.

Feature Summary

• Implements transition mode control for high-efficiency power factor correction
• Features low quiescent supply current for energy-efficient applications
• Designed for surface-mount technology integration

Applications

• Power factor correction stages in AC-DC adapters
• Universal input power supplies
• Consumer electronics power management systems

Procurement Notes

Verify the specific suffix 'D' corresponds to the tube packaging format when ordering. Confirm the operating temperature range meets the application requirements of +85°C maximum junction temperature. Ensure compatibility with the SOIC-8 footprint on the printed circuit board layout.

Selection Notes

Select this component for designs requiring transition mode PFC with minimal standby power consumption. The SOIC-8 package suits space-constrained layouts. Evaluate thermal performance at the upper limit of the specified operating temperature range to ensure reliability under full load conditions.

Part Context

This part belongs to the UCC28050 series of power factor correction controllers. It is distinct from other TI switchers like the UCC2805 or UCC28089, which serve different topologies such as current-mode PWM or primary-side regulation. The UCC28050D specifically targets PFC applications rather than general DC-DC conversion.
