AIC1642-50GXTR

AIC(Analog Integrations) · DC-DC Converters · SOT-89-3

AIC1642-50GXTR from AIC(Analog Integrations), in a SOT-89-3. 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; must be low impedance, so solder directly to the ground plane.
2 VOUT power_in IC supply pin; connect VOUT to the regulator output.
3 SW output Internal drain of the N-MOSFET switch that drives the inductor.
