TL1451ACPWR/5 TI PWM Controller | 2-Channel, 3.6V-50V, 500kHz

Product Overview

The TL1451ACPWR/5 from Texas Instruments is a dual-channel pulse-width modulation (PWM) controller designed for a wide range of power supply applications. It operates from an input voltage range of 3.6V to 50V and features a switching frequency up to 500kHz. The device includes two independent PWM channels with dead-time control, making it suitable for push-pull, half-bridge, and full-bridge topologies. Its low startup current (1.5mA typical) and wide operating temperature range (-40°C to +85°C) ensure reliable performance in demanding environments.
