MP3217DJ-LF-Z

Monolithic Power Systems · DC-DC Converters · TSOT-23-6

MP3217DJ-LF-Z from Monolithic Power Systems, in a TSOT-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 PGND power_in Power ground pin for the internal power switch return path, to be kept separate from the signal ground GND pin.
2 GND power_in Ground pin, where the input and output capacitor ground returns should be tied close to the device.
3 FB input Feedback input with a 1.24V reference voltage, connected to a resistor divider from the output.
4 EN input ON/OFF control input where a voltage above 2V turns the part on and below 0.8V turns it off, and floating EN to the input source gives automatic startup when unused.
5 IN power_in Input supply pin that must be locally bypassed, with an operating input voltage of 2.5V to 6V.
6 SW output Power switch output that is the drain of the internal MOSFET, to which the power inductor and output rectifier connect, with SW rated from VIN to 36V.
