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. |
