LM5039MH/NOPB TI PWM Controller | 20-HTSSOP | 100V, Push-Pull, Current Mode

Product Overview

The LM5039MH/NOPB is a high-voltage push-pull PWM controller from Texas Instruments, designed for isolated DC-DC converter applications. It integrates a 100V start-up regulator and operates with a wide input voltage range from 15V to 100V. The device features current-mode control with programmable slope compensation, adjustable dead-time, and synchronization capability. Housed in a 20-pin HTSSOP package with exposed pad for enhanced thermal performance, it is ideal for telecom, industrial, and automotive power systems requiring high efficiency and reliability.
