UCC28500DW Description

Short technical summary and product information.

The Texas Instruments UCC28500DW is an integrated circuit designed for active power-factor correction (PFC) and second-stage DC-to-DC conversion. It utilizes average current-mode control to shape the AC input line current waveform, achieving near-unity power factor. The device also incorporates peak current-mode control for the step-down power conversion.

 

Key features include a programmable oscillator, leading-edge/trailing-edge modulation for reduced output ripple, and low start-up supply current. The controller operates with a voltage range of 9.7V to 18V and an ambient temperature range of -40°C to 85°C. It is supplied in a 20-SOIC surface mount package.

 

This controller is suitable for applications requiring efficient power management and power factor correction. Its design combines PFC and downstream converter controls, offering accurate power limiting and improved feedforward line regulation.
