: Features two transistors capable of sinking or sourcing up to 200 mA (or 500 mA in some variants), offering flexibility for driving external loads. Wide Operating Voltage : Functions reliably with a supply voltage range of Pinout Configuration (16-Pin DIP/SOIC) The following pinout is standard for the TL494 controller Description 1IN+, 1IN- Inputs for the first error amplifier. Input for feedback control. Dead-time control comparator input. External capacitor/resistor to set oscillator frequency. Ground terminal. Collector and Emitter for transistor 1. Emitter and Collector for transistor 2. Positive supply voltage. OUTPUT CTRL Selects single-ended (GND) or push-pull (REF) mode. 5V reference output. 2IN-, 2IN+ Inputs for the second error amplifier. Typical Applications Wide Operating Voltage : Functions reliably with a
