HT7183STNR

Jiaxing Heroic Elec Tech · DC-DC Converters · SOT-23-6

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.
