LM2665M6X

Texas Instruments · DC-DC Converters · SOT-23-6

LM2665M6X from Texas Instruments, 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 V+ power_in In voltage-doubler mode: positive supply input (2.5 V to 5.5 V). In voltage-splitter mode: positive voltage output (V_IN/2). Absolute max V+ to GND is 5.8 V.
2 GND power_in Power supply ground reference for the device in both doubler and splitter configurations.
3 CAP- passive Negative terminal of the external flying (charge-pump) capacitor C1. Typically 3.3 µF, low-ESR (<0.3 Ω).
4 SD input Shutdown control input. Tie to GND for normal operation; drive high (>=40% of V+, min 2 V) to place device into 1 µA shutdown. Low threshold <=20% of V+ (0.8 V max).
5 OUT power_out In voltage-doubler mode: positive doubled voltage output (~2*V_IN), up to 40 mA. In voltage-splitter mode: positive supply input (1.8 V to 11 V). Absolute max OUT to GND is 11.6 V.
6 CAP+ passive Positive terminal of the external flying (charge-pump) capacitor C1. Typically 3.3 µF, low-ESR (<0.3 Ω).
