HT2307ARZ from HTCSEMI, in a ESOP-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 | passive | Bootstrap pin that is 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 for the converter, operating over 4.5V to 27V and bypassed to GND with a low-ESR capacitor. |
| 3 | SW | output | Switch output connected to the switching end of the inductor; the SW voltage is limited to VIN + 0.3 V absolute maximum. |
| 4 | GND | power_in | Ground reference pin, which must also be connected to the exposed pad. |
| 5 | FB | input | Feedback input regulated to 0.925V, connected to the output resistor divider to set the output voltage. |
| 6 | COMP | passive | Compensation pin for the error amplifier, where RCOMP is limited to 10kΩ maximum and CCOMP sets the loop zero. |
| 7 | EN | input | Enable input that turns the IC on above 2.7V and off below 1.1V (absolute maximum -0.3 to 5 V), and must not be left open. |
| 8 | SS | input | Soft-start control input where a capacitor from SS to GND sets the soft-start period, with 0.1uF giving 13 ms. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
