TL494CNSR Description

Short technical summary and product information.

The TL494CNSR is a fixed-frequency pulse-width modulation (PWM) control circuit from Texas Instruments, designed for use in DC-DC switching regulator applications. It supports multiple topologies including buck, boost, and flyback converters. The device operates from a supply voltage range of 7V to 40V, allowing flexibility in various power supply designs. The oscillator frequency is programmable from 1kHz to 300kHz via external timing components. The TL494CNSR is specified for an ambient temperature range of 0°C to 70°C. It is housed in a 16-pin SOIC (16SO) package, suitable for surface-mount assembly. The controller includes internal dead-time control, error amplifiers, and a precision reference, making it a versatile solution for regulated power supplies.
