# TP6841S6-1

**TECH PUBLIC** · DC-DC Converters · SOT-23-6L

TP6841S6-1 from TECH PUBLIC, in a SOT-23-6L. 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 | BST | passive | Bootstrap pin; connect a 100nF capacitor from this pin to SW (BST voltage rated VSW-0.3 to VSW+6 V). |
| 2 | GND | power_in | Ground. |
| 3 | FB | input | Feedback input; connect an external resistor divider from the output to FB and GND to set VOUT (0.8V typical reference, rated VSS-0.3 to VSS+6 V). |
| 4 | EN | input | Enable pin for the IC; drive high to enable the part, low to disable (rising threshold 1.3V typ, falling 1.2V typ, rated up to VSS+45 V). |
| 5 | VIN | power_in | Supply voltage, 4.5V to 40V operating range; bypass with a 22µF ceramic capacitor to GND. |
| 6 | SW | output | Inductor connection; connect an inductor between SW and the regulator output (SW voltage rated VSS-0.3 to VIN+0.3 V). |
