TL494CDR TI DC-DC Controllers
The TL494CDR is a pulse-width modulation (PWM) control circuit from Texas Instruments in 16-pin SOIC (D) package, designed for switching power supply control with push-pull or single-ended topologies. For selection, verify supply from 7V to 40V, oscillator frequency up to 300kHz, 5V reference output with ±5% accuracy, output current of 200mA per transistor, variable duty cycle up to 45% for push-pull operation, undervoltage lockout, double-pulse suppression, and operating temperature from 0°C to +70°C. Ideal for SMPS, DC-DC converters, UPS, battery chargers, and voltage-mode PWM control applications. In stock at HL Electronics – request a quote for fast delivery.
