TL494CDR TI PWM Controller | 16-SOIC | 40V, 200kHz, Push-Pull

Product Overview

The TL494CDR from Texas Instruments is a fixed-frequency pulse-width modulation (PWM) control circuit designed primarily for power supply control. It incorporates all the functions required in the construction of a pulse-width modulation (PWM) control circuit on a single chip. The device is primarily intended for use in switching power supplies and other power control applications. It features an internal oscillator, a dead-time control comparator, a pulse-steering flip-flop, a 5V reference regulator, and two error amplifiers. The TL494CDR operates from a supply voltage of up to 40V and can deliver up to 200mA of sink or source current per output. The device is available in a 16-pin SOIC package, making it suitable for compact designs.
