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.
