IW1710-01

Dialog Semiconductor · AC-DC Controllers And Regulators · SOIC-8

IW1710-01 from Dialog Semiconductor, 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 NC unconnected No connection.
2 VSENSE input Auxiliary voltage sense used for primary side regulation.
3 VIN power_in Rectified AC line average voltage sense.
4 SD input External shutdown control; connect to ground through a resistor if not used (see section 10.16).
5 GND power_in Ground reference for the controller.
6 ISENSE input Primary current sense used for cycle-by-cycle peak current control and limit.
7 OUTPUT output Gate drive output for the external MOSFET switch.
8 VCC power_in Power supply for control logic and voltage sense for power-on reset circuitry.
