# DIO6971TST6

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

DIO6971TST6 from DIOO, 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 | GND | power_in | Power ground. |
| 2 | SW | output | Inductor pin; connect this pin to the switching node of the inductor (absolute max VIN+0.3V). |
| 3 | VIN | power_in | Power input, 4.5V to 24V recommended supply range (28V absolute maximum). |
| 4 | FB | input | Output feedback pin; connect to the center point of the output resistor divider, VOUT=0.8*(1+R1/R2), with optional 10pF~47pF C2 to speed up transient response. |
| 5 | EN | input | Enable control; pull high to turn on and do not float. |
| 6 | BS | passive | Bootstrap pin; connect a capacitor (0.1µF recommended) and a resistor between SW and BS to form a floating supply across the high-side switch driver. |
