UCC38500DWTRG4 Description

Short technical summary and product information.

The Texas Instruments UCC38500DWTRG4 is an integrated circuit designed for active power-factor correction (PFC) preregulation and second-stage DC-to-DC conversion. It achieves near-unity power factor by shaping the AC input line current waveform to match the AC input line voltage using average current-mode control.

 

Key electrical specifications include an operating voltage range of 9.7V to 18V and a frequency of 100kHz. The device operates at an ambient temperature range of 0°C to 70°C. It is housed in a 20-SOIC package, suitable for surface mount applications.

 

This controller integrates features for both the PFC stage and the DC-to-DC converter, offering accurate power limiting and improved line regulation. The PFC stage utilizes leading-edge modulation, while the second stage is trailing-edge synchronized to minimize overlap between switches and reduce output capacitor ripple current.
