SGM6603-5.0YN6G from SGMICRO, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | passive | Boost and rectifying switch input. Connects to the external boost inductor (typ. 4.7 µH) between VCC/input source and this pin; internal boost + synchronous rectifier MOSFETs switch this node at ~1.2 MHz with up to 1.1A switch current limit. |
| 2 | GND | power_in | Device ground reference. Connect to the system ground plane with a short, low-impedance return for the input and output capacitors. |
| 3 | EN | input | Enable input. Drive to VCC (logic high) to enable the converter or to GND (logic low) to shut it down; input thresholds scale with VCC (e.g. VIH ≥ 2.6V for 4.2V < VCC ≤ 5.0V, VIL ≤ 0.6V). EN input current is <1 µA when clamped to GND or VCC. |
| 4 | NC | unconnected | No Connect on the SGM6603-5.0 fixed-output variant. Leave floating; output voltage is set internally to 5.0V. (On the SGM6603-ADJ variant this pin is FB, the feedback input.) |
| 5 | VOUT | power_out | Boost converter output. Regulated to 5.0V (fixed) with typical output accuracy ±3.8%; connect a 10 µF ceramic output capacitor to GND. Load disconnect during shutdown allows VOUT to fall to 0V without drawing input current. |
| 6 | VCC | power_in | Boost converter supply voltage / input. Operating input range 0.9V to 5.5V (min start-up ~1.1-1.3V depending on load); bypass to GND with a 10 µF ceramic input capacitor. Absolute maximum is 6V. |
