LM2736YMKX

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

LM2736YMKX from Texas Instruments, in a TSOT-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 BOOST input Boost voltage that drives the internal NMOS control switch; a bootstrap capacitor is connected between the BOOST and SW pins.
2 GND power_in Signal and power ground pin; place the bottom resistor of the feedback network as close as possible to this pin for accurate regulation.
3 FB input Feedback pin; connect FB to the external resistor divider to set output voltage.
4 EN input Enable control input; logic high enables operation and this pin must not be allowed to float or exceed VIN + 0.3 V.
5 VIN power_in Input supply voltage pin in the 3.0 V to 18 V range; connect a bypass capacitor to this pin.
6 SW output Output switch; connects to the inductor, catch diode, and bootstrap capacitor.
