TL494CN TI PWM Controller | 16-PDIP | 40V, 200kHz, 0.3A Output

Product Overview

The TL494CN from Texas Instruments is a fixed-frequency pulse-width modulation (PWM) control circuit designed primarily for power supply control. It integrates all the functions required for a push-pull or single-ended switching power supply, including an internal oscillator, error amplifiers, a dead-time control comparator, and a 5V reference. Housed in a 16-pin PDIP package, it operates from a supply voltage up to 40V and can deliver up to 200mA sink/source per output. The device is ideal for applications requiring high efficiency and precise regulation.
