HT1482ARZ
HTCSEMI · DC-DC Converters · SOP-8
HT1482ARZ from HTCSEMI, in a SOP-8. 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 | BS | power_out | Bootstrap pin that acts as the positive rail for the high-side switch gate driver, with a 0.01uF capacitor connected between BS and SW. |
| 2 | VIN | power_in | Input supply pin, to be bypassed to GND with a low ESR capacitor; the datasheet specifies an input supply range of 4.5V to 27V. |
| 3 | SW | output | Switch output pin, connected to the switching end of the inductor. |
| 4 | GND | power_in | Ground pin. |
| 5 | FB | input | Feedback input regulated to 0.925V, connected to the resistor divider between output and ground to set the output voltage. |
| 6 | COMP | passive | Compensation pin for the feedback loop, with networks defined in the Stability Compensation section. |
| 7 | EN | input | Enable input that turns the IC on above 2.7V and off below 1.1V; it must not be left open and a 100KΩ pull-up to Vin is recommended for startup. |
| 8 | SS | passive | Soft-start control input where a capacitor from SS to GND sets the soft-start period (0.1uF gives 15ms), and leaving it unconnected disables soft-start. |
