SGMICRO · Driver ICs · TSOT-23-6
SGM3732YTN6G 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 | passive | Converter switching node connected to the integrated low-side power MOSFET, rated -0.3V to 40V, with 1.35A peak current limit. |
| 2 | GND | power_in | Ground. |
| 3 | FB | input | Output feedback pin regulated at 200mV, where the LED current sense resistor RSET is connected. |
| 4 | CTRL | input | Control pin of the boost regulator used for enable control and digital PWM dimming (2kHz to 60kHz), with an internal 500kΩ pull-down resistor. |
| 5 | VOUT | input | Output and over-voltage protection pin with 38V typical OVP threshold, rated -0.3V to 40V. |
| 6 | VIN | power_in | IC supply; connect to a supply voltage between 2.7V and 5.5V. |
