UCC28512DW TI PFC/PWM Controller | 20-SOIC | BiCMOS, 100-250kHz

Product Overview

The UCC28512DW from Texas Instruments is a highly integrated, BiCMOS, combined Power Factor Correction (PFC) and Pulse Width Modulation (PWM) controller designed for offline power supplies. It operates at a fixed frequency range of 100kHz to 250kHz and is housed in a 20-pin SOIC package. This device simplifies the design of high-performance AC-DC converters by combining two control stages into one IC, reducing component count and board space.
