AP3783AK6TR-G1

Diodes Incorporated · AC-DC Controllers and Regulators · SOT-26

AP3783AK6TR-G1 from Diodes Incorporated, in a SOT-26. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CS input Current sense input. The IC turns off the external power MOSFET when the voltage on this pin exceeds the internal peak current sense threshold (VCS_H typ 900 mV at full load). Also used with an internal 260 Ω line compensation resistor.
2 GND power_in Ground reference for the controller.
3 VCC power_in Supply voltage input for the IC (absolute max -0.3 to 35 V; startup threshold typ 15.5 V; minimum operating voltage typ 6.8 V). A low-ESR bypass capacitor should be placed as close as possible to this pin.
4 FB input Feedback input from the auxiliary winding divider. CV and CC regulation are realized based on the sampled voltage on this pin (VFB typ 4.01 V in closed loop, VFB(OVP) typ 7.5 V). Absolute max -0.4 to 10 V.
5 DRI output Gate driver output to drive the external power MOSFET (gate voltage typ 13 V, high source current typ 110 mA, low source current typ 20 mA, sink resistance typ 6.5 Ω).
6 CPC passive Cable compensation pin. A ~50 nF capacitor should be connected to this pin. Voltage on CPC is linear with load and is used for cable voltage drop compensation and audio noise suppression. Absolute max -0.3 to 7 V.
