TL1451CN TI PWM Controller | 16-PDIP | Dual Channel, 3.6V-50V

Product Overview

The TL1451CN is a dual-channel pulse-width modulation (PWM) controller from Texas Instruments, designed for a wide range of power supply applications. It operates from a supply voltage of 3.6V to 50V and features an adjustable oscillator frequency up to 500 kHz. The device includes two independent PWM channels with dead-time control, making it suitable for push-pull, half-bridge, and full-bridge topologies. Housed in a 16-pin PDIP package, the TL1451CN offers reliable performance for industrial and automotive power systems.
