UC3845AN

XBLW · AC-DC Controllers And Regulators · DIP-8

UC3845AN from XBLW, in a DIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 COMP output Error amplifier compensation pin; connect external compensation components to this pin to modify the error amplifier output.
2 VFB input Inverting input to the internal error amplifier, used to control the power converter voltage-feedback loop for stability.
3 ISENSE input Primary-side current sense pin; connect to the current sensing resistor, and the PWM uses this signal to terminate OUTPUT switch conduction.
4 RT/CT passive Connect timing resistor RRT to VREF and timing capacitor CCT to GROUND from this pin to set switching frequency and maximum output ratio, up to 500kHz maximum frequency.
5 GND power_in Ground.
6 OUTPUT output Gate drive for the external MOSFET; peak currents of up to 1 A are sourced and sunk by this pin.
7 VCC power_in Power supply pin that provides power to the device.
8 VREF power_out Reference voltage pin used to provide charging current to the oscillator timing capacitor through the timing resistor.
