HT1541ARTZ 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 | output | Power switch output, the drain of the internal MOSFET, to which the power inductor and output rectifier connect; SW can swing between GND and 22V (absolute maximum on the SW pin is 25V). |
| 2 | GND | power_in | Ground reference pin; the ground returns of C1 and C2 should be tied close to this pin. |
| 3 | FB | input | Feedback input regulated to 1.25V (1.21V to 1.29V); a resistor divider sets the output voltage, with a 47kΩ to 100kΩ series resistor recommended in series with the FB pin. |
| 4 | EN | input | Regulator on/off control input where a high level enables the converter and a low level disables it, and the pin must not be left floating (it can be tied to IN for automatic startup). |
| 5 | IN | power_in | Input supply pin with a 2.5V to 6V operating range that must be locally bypassed, using a ceramic input capacitor of 4.7µF or greater placed close to the pin. |
