NCP1654BD133R2G

onsemi · AC-DC Controllers & Regulators · SOP-8

NCP1654BD133R2G from onsemi, in a SOP-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 GND power_in Ground pin of the IC; the datasheet gives no further function text.
2 Vin power_in Multiplier voltage pin providing VM for PFC duty-cycle modulation, with input impedance set by external RM, and average-current mode when an external CM is connected (otherwise peak-current mode).
3 CS input Current sense input that sources a current ICS proportional to inductor current for OCP, OPL and duty-cycle modulation, with OCP activated and the drive disabled when ICS exceeds 200 µA.
4 VBO input Brown-out input that senses a signal proportional to average input voltage, turning off the driver when VBO falls below VBOL (0.7 V typ) until it exceeds VBOH (1.30 V typ), and also used for overpower limitation and duty-cycle modulation.
5 Vcontrol output Control voltage / soft-start pin connected to type-2 compensation components to limit Vcontrol bandwidth typically below 20 Hz, with no output when Vcontrol is below Vcontrol(min) and a slow power increase at start (soft-start).
6 VFB input Feedback / shutdown pin receiving a signal proportional to the output voltage, with OVP activated above 105% VREF and low-consumption shutdown entered below 8% VREF.
7 VCC power_in Positive supply of the IC that starts typically above 10.5 V and turns off below 9 V, with an operating range of 9 V up to 20 V after start-up.
8 DRV output Totem pole gate drive output with ±1.5 A capability for driving high gate charge power MOSFETs.
