ME2159BM6G from MICRONE, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	LX	output	Power switch (drain) node of the internal N-channel power MOSFET; connects to the boost inductor and Schottky diode anode. Rated for 2A peak switch current with 0.18Ω RDS(on) and a maximum voltage of 16V (absolute max 12V per Abs Max table).
2	GND	power_in	Device ground return. Should be tied directly to the input and output capacitor grounds on a common ground plane for low-noise operation.
3	FB	input	Feedback input to the internal error amplifier; regulates to VFB = 0.6V (±2%). Output voltage is set by an external resistive divider: VOUT = 0.6 × (1 + R1/R2). If FB drops below ~0.3V a short-circuit comparator engages.
4	EN	input	Chip enable, active high. VEN ≥ 1.5V enables the converter; VEN ≤ 0.6V puts the device in shutdown (typ. 0.1µA quiescent). Do not leave floating; absolute max VIN referenced.
5	VIN	power_in	Main supply input, 2.5V to 5.5V operating range (absolute max 6.0V). UVLO threshold typ. 2.15V with 0.08V hysteresis. Bypass with a low-ESR ceramic capacitor (e.g., 22µF) placed close to the pin.
6	NC	unconnected	No internal connection. May be left floating or tied to GND for PCB routing convenience.
