HT1488ARTZ

HTCSEMI · DC-DC Converters · SOT-23-5

HT1488ARTZ 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 Chip enable: drive above 1.5V to turn the part on and below 0.3V to turn it off; do not leave floating.
2 GND power_in Ground pin.
3 SW passive Power switch output (LX) connecting to the inductor, tied to the drains of the internal P-channel and N-channel MOSFET switches.
4 VIN power_in Power supply input (2.5V to 5.5V), must be closely decoupled to GND with a 10µF or greater ceramic capacitor.
5 FB input Output voltage feedback pin; an internal resistive divider scales the output voltage for comparison to the internal 0.6V reference.

CAD (KiCad official)

  • Symbol: HT1488ARTZ
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ht1488artz-etched.step / ht1488artz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht1488artz.step / ht1488artz.glb are the bare package body.
