HT7183STNR from Jiaxing Heroic Elec Tech, 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 | power_out | Switching node of the converter, connected to the internal power switch (RDS(on) 120 mΩ); the absolute maximum rating on SW is -0.3 V to 20 V, and the inductor should be placed as close as possible to this pin. |
| 2 | GND | power_in | Ground reference for the device; the thermal pad must be soldered to a large ground plane with thermal vias, and the input and output capacitors should be connected to it with low impedance. |
| 3 | FB | input | Voltage feedback input with a 0.6 V reference, where VOUT = 0.6 V × (1 + RUP/RDN) and the RUP/RDN divider should sit as close as possible to this pin; the absolute maximum rating on FB is -0.3 V to 6 V. |
| 4 | EN | input | Enable logic input where a logic high above 1.8 V enables the device and a logic low below 0.6 V puts it into shutdown; it has an internal 800 kΩ pull-down and an absolute maximum rating of -0.3 V to 6 V. |
| 5 | VCC | power_in | Power supply input with a recommended range of 2.6 V to 5.5 V and an absolute maximum of 6 V; the UVLO threshold is 2.4 V rising and 2.2 V falling. |
| 6 | OC | input | Adjustable peak switch current limit, set by a resistor from this pin to GND, with the limit to be kept below 3 A for the SOT23-6 package. |
