UCC38501N TI PFC/PWM Controller | 20-PDIP | 100kHz, 15V Gate Drive

Product Overview

The UCC38501N from Texas Instruments is a high-performance BiCMOS power factor correction (PFC) and pulse-width modulation (PWM) controller combo IC. It integrates a boost PFC controller and a PWM controller in a single 20-pin PDIP package, designed for offline power supplies requiring high power factor and low total harmonic distortion (THD). The device operates at a fixed frequency of 100kHz and provides a 15V gate drive for external MOSFETs. It features a leading-edge modulation technique for the PFC stage and trailing-edge modulation for the PWM stage, reducing ripple current and simplifying EMI filtering. The UCC38501N is ideal for applications such as 5G base station power supplies, industrial power systems, and high-end server power units.
