Tl494 buck schematic
WebOct 5, 2024 · The TL494 IC has 8 functional blocks, which are shown and described below. The 5V internal reference regulator output is the REF pin, which is pin-14 of the IC. The reference regulator is there to provide a stable supply for internal circuitry like the pulse-steering flip-flop, oscillator, dead-time control comparator, and PWM comparator. WebJan 14, 2024 · For that to happen you need to connect the clock output to one input of an added 2-input OR gate, and an added (new) zero-current comparator signal to the other OR gate input, with the OR output going to the FF set input so that either signal will turn the switch ON.
