UCC29950D

Overview

The UCC29950D is a power factor correction (PFC) controller manufactured by Texas Instruments, designed for continuous conduction mode (CCM) applications. It operates within a switching frequency range of 87 kHz to 109 kHz and utilizes a 16-SOIC package. The device integrates control logic for AC/DC conversion systems requiring main PFC functionality.

Feature Summary

• Supports continuous conduction mode (CCM) operation for power factor correction
• Integrated control logic for AC/DC converter topologies

Applications

• AC/DC power supplies with main PFC stage
• Power factor correction circuits in offline SMPS

Procurement Notes

Verify the specific revision level and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the 16-SOIC package matches your PCB footprint requirements. Ensure the component meets all relevant environmental regulations for your target market.

Selection Notes

Select this component for designs requiring CCM PFC control with a fixed operating frequency range between 87 kHz and 109 kHz. It is suitable for standard AC/DC conversion architectures where main PFC functionality is required. Evaluate thermal management needs associated with the SOIC-16 package.

Part Context

This part belongs to the UCC299 series from Texas Instruments, which focuses on AC/DC and PFC solutions. It serves as a dedicated controller for power factor correction stages in offline switch-mode power supplies, distinct from general-purpose gate drivers or voltage regulators.
