# HT6302ARTZ

**HTCSEMI** · DC-DC Converters · SOT-23-5

HT6302ARTZ from HTCSEMI, in a SOT-23-5. 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 | power_out | Boost switch output, connect the 10uH inductor here; absolute maximum voltage is 65 V and maximum current is 3 A. |
| 2 | GND | power_in | System ground pin. |
| 3 | FB | input | Voltage feedback input; the control loop regulates this pin to 1.2 V. |
| 4 | EN | input | Boost enable input; absolute maximum voltage is 6 V and the typical application shows a 0~5.5 V enable signal. |
| 5 | VIN | power_in | Input voltage bias pin; recommended input range is 3.0 V to 60 V. |

## CAD (KiCad official)

- Symbol: `HT6302ARTZ`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `ht6302artz-etched.step` / `ht6302artz-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ht6302artz.step` / `ht6302artz.glb` are the bare package body.
