TL494 PWM Controller | TI The TL494 device incorporates all the functions required in the construction of a pulse width modulation (PWM) control circuit on a single chip. Designed primarily for power supply control, this device offers the flexibility to tailor the power supply control circuitry to a specific application. TL494 Class D Amplifier SMPS 390W 32V Electronics ... TL494 Audio amplifier switch mode power supply smps. TAS5611A Class D Amplifier Circuit Project The performance of the power unit should be about 400 Watts smps.The power source may be elected by the classic or switched. Because of the size and weight of the transformer of the classical sources is elected a switching power supply. 15 48V Bench SMPS Uzzors2k Hobby Projects Site The output section in the TL494 consists of two transistors, which cannot drive a transformer directly. So by using some pull up resistors it can drive a full bridge of small BJTs, which can then drive a GDT. The design of the full bridge and TL494 outputs is such that during deadtime both primary leads of the GDT will be held low. Modifing a TL494 SMPS current limiting. Hi there. I'd like to modify this 12V 30A which uses the TL494 PWM controller IC for battery charging purposes: There is a voltage adjust pot available which is fine but now I want to be able the current with a variable pot here is the reference schematic from it's datasheet: tl494 circuit Archive Electronics Projects Circuits TL494 Audio amplifier switch mode power supply smps . TAS5611A Class D Amplifier Circuit Project The performance of the power unit should be about 400 Watts smps. The power source may be elected by the classic or switched. TL494, NCV494 SWITCHMODE Pulse Width Modulation Control ... The TL494 is a fixed−frequency pulse width modulation control circuit, incorporating the primary building blocks required for the control of a switching power supply. AN983 D A Simplified Power Supply Design Using the TL494 ... The TL494 provides the pulse width modulation control for the power supply. The minimum output dead–time is set to approximately 4% by grounding Pin 4 through R5. The soft start is controlled by C5 and R5. Transistor Q11 is used to discharge C5 and to inhibit the operation of the power supply if a low ac line voltage condition is sensed ...

It uses TL494. PSU works, but this 800 Hz oscillations are present. It had a failed output filter caps, I have replaced them all with high quality low ESR Japanese caps (this was like 2 years ago).
