TPS61040DDCR

Texas Instruments · LED Drivers · SOT-23-5

TPS61040DDCR 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 Switch pin connected to internal N-channel power MOSFET drain; attach external inductor and Schottky diode to this pin; maximum voltage rating 30V.
2 GND power_in Ground reference.
3 FB input Feedback input pin for connecting external voltage divider to program output voltage up to 28V; input bias current 1μA typical.
4 EN input Enable control input; pull to ground to enter shutdown mode with quiescent current below 1μA; pin must not be left floating and must be terminated.
5 VIN power_in Power supply input; operating voltage range 1.8V to 6V.
