TL1454ACDBR TI PWM Controller | 16-SSOP | Dual Channel, 3.6V-50V

Product Overview

The TL1454ACDBR from Texas Instruments is a dual-channel pulse-width modulation (PWM) control circuit designed for a wide range of power supply applications. It integrates two independent PWM controllers in a compact 16-pin SSOP package, offering high efficiency and flexibility. The device operates over a supply voltage range of 3.6V to 50V, making it suitable for both low-voltage and high-voltage systems. With a maximum duty cycle of 100% and a typical oscillator frequency of 500 kHz, the TL1454ACDBR provides precise control for DC-DC converters, battery chargers, and other power management circuits.
