HT3302ARTZ from HTCSEMI, 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 | output | Power switch output of the boost converter; the datasheet gives an absolute maximum VSW of -0.5 to 40 V and an output voltage range of VIN to 35 V. |
| 2 | GND | power_in | Ground; the datasheet recommends connecting it to a strong ground plane for heat sinking and noise protection. |
| 3 | FB | input | Feedback input regulated to 300 mV (VFB 291 to 309 mV); the LED current is set as I = 300 mV / R1 with an external sense resistor. |
| 4 | EN | input | Chip enable with VEN_H minimum 1.5 V and VEN_L maximum 0.4 V, which also accepts PWM dimming up to 200 kHz. |
| 5 | NC | unconnected | Not connected. |
| 6 | IN | power_in | Power supply input with an operating range of 2.5 to 7.5 V and an absolute maximum of -0.3 to 8 V. |
