# TP8204HS6-B

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

TP8204HS6-B from TECH PUBLIC, 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 | GND | power_in | Device ground return. Connect to system ground plane; carries switching return currents. |
| 2 | LX | output | Switching node. Internal high-side and low-side MOSFETs connect here; drive the external inductor from LX. Swings between GND and VIN at 500kHz. |
| 3 | IN | power_in | Power supply input. 4.5V to 17V input voltage range. Bypass with a low-ESR ceramic capacitor (e.g. 22uF) close to the pin. |
| 4 | FB | input | Adjustable-version feedback input. Connect FB to the center point of the external resistor divider. Regulated to 0.8V typical (0.780V min / 0.820V max). |
| 5 | EN | input | Enable input. Drive logic-high (Vih >= 1.5V) to enable the IC; drive logic-low (Vil <= 0.5V) to disable the IC and enter micro-power shutdown mode (~1uA). Absolute max 6V. |
| 6 | BS | passive | Bootstrap pin for the high-side MOSFET gate driver. Connect a capacitor (typ. 1uF) between LX and BS to form a floating supply across the high-side switch driver. |
