TL494IDR TI DC-DC Controllers
The TL494IDR is a pulse-width modulation (PWM) control circuit from Texas Instruments in SOIC-16 surface-mount package, designed for switching power supply control with push-pull or single-ended topologies . For selection, verify supply voltage from 7V to 40V, oscillator frequency up to 300kHz, 5V reference voltage output with ±5% accuracy, output current of 200mA per transistor, and operating temperature from -25°C to +85°C . Features include variable duty cycle up to 45% for push-pull operation, undervoltage lockout, double-pulse suppression logic, totem-pole outputs for direct MOSFET/IGBT drive, and dead-time control. Ideal for switching power supplies, DC-DC converters, uninterruptible power supplies (UPS), battery chargers, motor control, and any voltage-mode PWM control application requiring high-performance switching regulation .
