MX1210T

Wuxi Maxinmicro · AC-DC Controllers And Regulators · SOT-23-6

MX1210T from Wuxi Maxinmicro, in a SOT-23-6. 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 controller, to be routed as a separate ground path per the datasheet layout guidelines.
2 FB input Feedback input whose voltage, together with the CS signal, sets the PWM duty cycle; absolute maximum input is -0.3 V to 7 V.
3 DMAG input Demagnetization input that senses input and output voltages from the auxiliary winding; absolute maximum input is -0.3 V to 7 V.
4 CS input Current sense pin, connected through resistors to ground; absolute maximum input is -0.3 V to 7 V.
5 VDD power_in Power supply pin with a recommended supply range of 10-48 V and an absolute maximum DC supply voltage of 60 V.
6 GATE output Gate driver output for the external MOSFET, with gate high voltage of 8.0 V typical (at VDD=15 V, Io=20 mA) and gate clamp voltage of 11.5 V.
