XT1861B362MR-G

NATLINEAR · DC-DC Converters · SOT-23

XT1861B362MR-G from NATLINEAR, in a SOT-23. 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 device; the datasheet gives no electrical limit for this pin.
2 LX output Switch pin driving the boost inductor; the maximum current in the LX pin is 1000 mA and the maximum voltage on VLX is 6.5 V.
3 VOUT power_out Output pin of the boost converter; the maximum supply voltage on VOUT is 6.5 V and the output voltage is set 1.8 V to 5.0 V in 0.1 V steps.
