HT8097ARTZ

HTCSEMI · DC-DC Converters · SOT-23-5

HT8097ARTZ 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 EN input Enable control input: a logic-high (VIH min 1.5V) enables the converter and a logic-low (VIL max 0.4V) forces shutdown mode.
2 GND power_in Power ground return for the converter.
3 LX output Switch node connecting the internal high-side and low-side power MOSFETs to the output inductor.
4 VIN power_in Supply voltage input; the HT8097A operates from a 2.7V to 5.5V input.
5 FB input Feedback voltage input; an external resistor divider from the output to GND tapped at FB sets the output voltage against the 0.6V reference.
