NCP43080ADR2G

onsemi · AC-DC Controllers And Regulators · SOIC-8

NCP43080ADR2G from onsemi, in a SOIC-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 VCC power_in Supply voltage pin for the controller; the datasheet gives an operating range up to VCC = 35 V in the features list.
2 MIN_TOFF input Adjusts the minimum off-time period through a resistor connected to ground.
3 MIN_TON input Adjusts the minimum on-time period through a resistor connected to ground.
4 LLD input Input that modulates the driver clamp level and/or turns the driver off during light-load conditions.
5 NC unconnected Leave this pin open or tie it to ground; for this variant (ver. A) it has no function.
6 CS input Current sense pin that detects current flowing through the SR MOSFET and/or its body diode, with a basic turn-off detection threshold of 0 mV and an optional series resistor to lower the threshold.
7 GND power_in Ground connection for the SR MOSFET driver, VCC decoupling, and the minimum on/off time and LLD inputs, to be wired directly to the MOSFET source using a Kelvin connection.
8 DRV output Driver output for the SR MOSFET.
