IK5302DT from IKSEMICON, 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 | GND | power_in | Reference, internal controller and analogue part ground for the IC. |
| 2 | Vin | power_in | Input supply voltage rated 4.5 V to 18 V; the IC starts operating when Vin rises above the UVLO threshold (3.6 V rising, 3.4 V falling). |
| 3 | EN | input | Active-high enable pin with 0.6 V off threshold and 2 V on threshold; it must not be left open, so connect to Vin for normal operation or to GND to disable. |
| 4 | FB | input | Error amplifier feedback input; a resistive divider between Vout and GND sets the output voltage against the 0.8 V reference (VFB typ. 800 mV). |
| 5 | COMP | passive | External loop compensation node, typically a series RC network to GND. |
| 6 | VCC | power_out | Internally generated supply for the control circuitry; a ceramic capacitor of about 0.1 to 1 uF should be connected between VCC and GND. |
| 7 | LX | output | PWM switching output connected to the output inductor (absolute maximum -0.3 V to +20 V to GND). |
| 8 | BS | passive | High-side bootstrap capacitor connection; a ceramic capacitor of 10 to 22 nF should be connected between BS and LX (BS to LX maximum 6 V). |
