TL1454ACN TI PWM Controller | 16-PDIP | Dual Channel, 3.6V-50V

Product Overview

The TL1454ACN from Texas Instruments is a dual-channel pulse-width modulation (PWM) controller designed for a wide range of power supply applications. Housed in a 16-pin PDIP package, this device integrates two independent PWM control circuits with a common oscillator, providing flexibility and efficiency in system design. It operates over a supply voltage range of 3.6V to 50V, making it suitable for both low-voltage and high-voltage systems. The TL1454ACN features an internal reference voltage of 2.5V, an oscillator frequency range up to 500 kHz, and a maximum duty cycle of 100%. Its robust design includes undervoltage lockout (UVLO) and a dead-time control function to prevent cross-conduction. This controller is ideal for push-pull, half-bridge, and full-bridge topologies, offering reliable performance in industrial, automotive, and telecommunications applications.
