SGM6603-ADJYN6G

SGMICRO · DC-DC Converters · SOT-23-6

SGM6603-ADJYN6G from SGMICRO, in a SOT-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 Boost and rectifying switch node; the datasheet names it the boost and rectifying switch input and gives a 1A switch current limit (0.8 to 1.3A).
2 GND power_in Ground reference for the device.
3 EN input Enable input: logic 1 (VCC) enables the converter and logic 0 (GND) disables it; the EN input low and high thresholds depend on VCC (for example, VIH is 2.6V minimum at 4.2V < VCC ≤ 5.0V).
4 FB input Output voltage feedback pin used with an external resistor divider to program VOUT for the ADJ version; the feedback voltage is 485 to 515mV with a 500mV typical value.
5 VOUT power_out Boost converter output, with output voltage range 2.5V to 5.5V and output voltage clamping at 6V.
6 VCC power_in Boost converter supply voltage, with input voltage range after start-up of 0.9V to 5.5V.
