HTCSEMI · DC-DC Converters · SOT-23-6
HT63032ARTZ 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 | passive | Internal power switch node, connected externally to the power inductor and Schottky diode. |
| 2 | GND | power_in | Ground pin. |
| 3 | FB | input | Feedback input connected to the external sense resistor; output current IOUT = VFB/Rsence (A), with VFB typically 0.2V. |
| 4 | EN | input | Enable and dimming input accepting DC or PWM square wave; rising threshold above 0.5V enables, falling below 0.4V shuts down, with an internal 800K pulldown. |
| 5 | OVP | input | Overvoltage protection input connected to a resistor divider from the output to ground; trip point typically 1.2V and recovery 0.86V. |
| 6 | VIN | power_in | Driver supply input with 3.0V to 60V recommended range; bypass to GND with a 4.7uF or larger ceramic capacitor placed close to the pin. |
