SGM3752YTN6G from SGMICRO, 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 | SW | output | Switch pin connected to the drain of the internal N-channel power FET, rated from -0.3V to 40V on SW. |
| 2 | GND | power_in | Ground; the signal ground should connect to the power ground via a single point close to the GND pin. |
| 3 | FB | input | Feedback input for current that regulates to VFB of 200mV at full PWM duty cycle, with the sense resistor RSET connected between FB and GND. |
| 4 | CTRL | input | PWM dimming input with logic high above 1.5V and logic low below 0.4V, where CTRL held low for more than 2.5ms enters shutdown. |
| 5 | NC | unconnected | No connection. |
| 6 | VIN | power_in | Input supply pin, operating from 2.7V to 5.5V with UVLO at 2.2V (typ) on falling VIN. |
