LM2681M6X

Texas Instruments · Charge Pumps · SOT-23-6

LM2681M6X from Texas Instruments, 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 V+ power_in Positive supply input for voltage-doubler operation, specified from 2.5 V to 5.5 V; in voltage-split mode this pin becomes the positive voltage output.
2 GND power_in Power supply ground input, which also serves as the ground reference for the internal oscillator that runs from OUT to GND (OUT to GND must exceed 1.8 V for the oscillator to operate).
3 CAP− passive Connect to the negative terminal of the charge-pump capacitor C1.
4 GND power_in Second power supply ground input, same function as pin 2.
5 OUT power_out Positive voltage output in doubler mode (2V+ at no load) with 30 mA maximum continuous output current; absolute maximum ratings are 11.6 V to GND and 5.8 V from OUT to V+, and in split mode this pin is the supply input.
6 CAP+ passive Connect to the positive terminal of the charge-pump capacitor C1.
