Description The UC3842/UC3843/UC3844/UC3845 are fixed frequencycurrent-mode PWM controller. They are specially designed for Off-Line and DC to DC converter applications with minimum external components.

-there will be a separate , small 10V(out) SMPS which will supply the UC3843 (this small SMPS is a SEPIC and can produce 10V(out) from 2.1V(in) or 30V(in) etc) The 10V zener is here as in that schematic the V(in) is 30V, above the maximum V(in) of UC3843.

UC3843 IC is a current Mode PWM Controller, meaning it can be used to provide a constant current by varying the output voltage to the load.
  • If the power supply has short-circuit before starting output, then power supply can be normally started and running continuously for a long time. If power supply has a sudden short-circuit during running with load, then power supply would automatically stop output and gives sound alarm, LEDs on front panel would display corresponding alarm code.
  • A key aspect of switch mode power supply regulators is the input and output filtering. This is a particular issue because of the switching that occurs at the input. In reality ripple voltage on the output is dependent not only on the output smoothing, but more importantly on an input filter capacitor.
  • Dec 14, 2020 · 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.

    If you have been repairing switch mode power supplies (SMPS), I’m sure you have definitely come across the famous UC3842 Pulse Width Modulation (PWM) IC. This IC generates a pulse waveform to switch the Power Mosfet Transistor. Whenever a SMPS have problem one of the component that we directly replaced was the UC3842 IC. The reason we

    The 56 K, 2 Watt Resistor only supplies a Start Up power for the UC3843. Once the circuit is running, the Uc3843 actually gets its power from this 3rd winding. I used 6 turns of 28 AWG. Resistor "IX" is a 1 or 2 watt Current Limit Resistor to protect the IC.

    Jun 17, 2016 · The remote-sense terminals on a dc load and dc power supply can ensure input and output voltage settings are accurate during tests of input turn-on and turn-off voltage levels and timing. Turn-on time is the period from the point the minimum input voltage is reached to the top time the output voltage is within the output regulation limits.

Part Number: UC3843. Hi, I want to design an ISOLATED flyback based, power supply using UC3843 with following specs:-Input = 20VDC to 70VDC. Output : a) 5V / 0.2A. b) 5V / 0.2A and 27V / 0.15 A (these 2 outputs have common ground) Kindly advise a solution using UC3843. Regards. Atul Bhakay
Aug 22, 2019 · Transformerless Power Supply circuit. A very crude LED driver circuit can be build using the Capacitor Dropper method, just like we did in our previous Transformerless power supply project. While these circuits are still being used in some very cheap electronic products it suffers from a lot of drawback which we will discuss later.
