UC2544N TI Power Management IC | 18-PDIP | Dual PWM Controller, 40V

Product Overview

The UC2544N from Texas Instruments is a high-performance dual PWM controller designed for a wide range of power conversion applications. Housed in an 18-pin PDIP package, this IC integrates two independent PWM controllers with precise dead-time control, making it ideal for push-pull, half-bridge, and full-bridge topologies. The device operates from a supply voltage up to 40V and features undervoltage lockout, soft-start, and programmable oscillator frequency. Its robust design ensures reliable operation in demanding environments such as industrial power supplies, telecom equipment, and automotive systems.
