IK5302DT

IKSEMICON · DC-DC Converters · SOP-8

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).
