UCC28516DW TI PFC/PWM Controller | 20-SOIC | 250kHz, 10.5V-15V

Product Overview

The UCC28516DW from Texas Instruments is a highly integrated, combined Power Factor Correction (PFC) and Pulse Width Modulation (PWM) controller designed for offline power supplies. It operates at a fixed frequency of 250kHz and is housed in a 20-pin SOIC package. This device simplifies the design of AC-DC converters by providing all necessary functions for a two-stage PFC and PWM control in a single IC, reducing component count and board space.
