HT8008ARTZ

HTCSEMI · DC-DC Converters · SOT-23-5

HT8008ARTZ 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 RUN input Chip enable pin: drive RUN above 1.5V to turn the part on and below 0.3V to turn it off, and do not leave it floating.
2 GND power_in Ground pin.
3 SW output Power switch output and switch node connection to the inductor, connecting to the drains of the internal P-ch and N-ch MOSFET switches.
4 VIN power_in Power supply input that must be closely decoupled to GND with a 4.7µF or greater ceramic capacitor.
5 FB input Feedback pin: an internal resistive divider scales the output voltage for comparison to the internal 0.6V reference.
