LM2611BMFX

Texas Instruments · DC-DC Converters · SOT-23-5

LM2611BMFX from Texas Instruments, in a SOT-23-5. 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 SW output Drain of internal switch, -0.4 V to 36 V; connect at node of input inductor and Cuk capacitor.
2 GND power_in Analog and power ground.
3 NFB input Negative feedback input, -6 V to 0.4 V; set output voltage via external resistor divider.
4 SHDN input Shutdown control input, -0.4 V to 14.5 V; high enables device, low disables.
5 VIN power_in Analog and power input, 2.7 V to 14 V supply range; filter high frequency noise with 0.1-µF capacitor.
