MX1210P

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

MX1210P 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 for the controller, which the datasheet's terminal table identifies as the IC ground reference.
2 FB input Feedback input whose voltage, together with the CS pin, sets the PWM duty cycle; the absolute maximum input voltage is -0.3 to 7V.
3 DMAG input Demagnetization input that senses input and output voltages from the auxiliary winding; the absolute maximum input voltage is -0.3 to 7V.
4 CS input Current sense pin, connected through resistors to ground, with an absolute maximum input voltage of -0.3 to 7V.
5 VDD power_in Power supply pin with a recommended VDD supply range of 10-48V and an absolute maximum DC supply voltage of 60V.
6 GATE output Gate driver output for the external MOSFET, with a gate clamp voltage of 11.5 V (typical).
