TL1451AMFKB TI PWM Controller | Dual Channel | 3.6V-50V, 500kHz

Product Overview

The TL1451AMFKB is a dual-channel pulse-width modulation (PWM) controller from Texas Instruments, designed for high-performance power supply applications. It integrates two independent PWM control circuits with a common oscillator, providing precise regulation and flexibility. Operating from a supply voltage range of 3.6V to 50V, it is suitable for a wide variety of DC-DC converter topologies including boost, buck, flyback, and forward converters. The device features a 500kHz maximum oscillator frequency, dead-time control, and undervoltage lockout, making it ideal for industrial, automotive, and telecommunications power systems.
