ISL9111AEH50Z-T7A

RENESAS · DC-DC Converters · SOT-23-6

ISL9111AEH50Z-T7A from RENESAS, in a SOT-23-6. 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 SW bidirectional The SW pin is the switching node of the power converter and connects one terminal of the inductor, with the other terminal going to power input.
2 GND power_in GND is the system ground pin.
3 EN input EN is an active-high logic input that enables the device; when asserted low the device is completely disabled and current is blocked between SW and the output, and it must be tied either high or low.
4 FAULT output FAULT is a fault output that goes logic LOW under a number of fault conditions listed in Table 1 on page 10.
5 VOUT power_out VOUT is the device output pin, with a 5.0V fixed output for this variant and an output voltage range of up to 5.25V.
6 VIN power_in VIN is the device input supply pin, and the datasheet calls for a 4.7µF ceramic capacitor connected to power ground at this pin; recommended VIN is 0.8V to VOUT - 200mV.
