# DIO6602ST6

**DIOO** · DC-DC Converters · SOT-23-6

DIO6602ST6 from DIOO, 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 | passive | Switch pin; connect the inductor between VIN and this pin (absolute maximum -0.3 to 6 V DC, -0.3 to 7 V pulsed <100 ns). |
| 2 | GND | power_in | Power ground. |
| 3 | /SHDN | input | Logic-controlled shutdown input; high = normal operation, low = IC shutdown. |
| 4 | FB | input | Feedback input to the error amplifier; connect the resistor divider tap to this pin. |
| 5 | VOUT | power_out | Output voltage sense and drain of the internal synchronous rectifier. |
| 6 | VIN | power_in | Input supply pin (operates down to 0.7 V supply; application circuit shows 0.5-5 V input). |
