LP6222B6F

LOWPOWER · DC-DC Converters · SOT-23-6

LP6222B6F from LOWPOWER, 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	LX	passive	Switching node pin connected to the inductor and output diode; keep traces short and do not add capacitance (switch rated to 12V, 4.8A current limit).
2	GND	power_in	Ground.
3	FB	input	Regulation feedback input connected to an external resistive divider from the output to set the output voltage (0.6V typical feedback voltage).
4	EN	input	Regulator on/off control input: logic high (VEN>1.4V) turns on the regulator, logic low (VEN<0.4V) puts it into low current shutdown mode.
5	VIN	power_in	Power supply pin (2.5V to 5.5V supply range).
6	ISET	passive	Sets the LX peak current limit via a resistor to GND (10K to 96K gives 4.8A to 0.5A, IOCP=48000/R3); keep traces short and do not add capacitance.
