ADP1613ARMZ-R7 from Analog Devices, in a MSOP-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 | COMP | input | Compensation input; connect a series resistor-capacitor network from COMP to GND to compensate the regulator. |
| 2 | FB | input | Output voltage feedback input; connect a resistive divider from the output voltage to FB to set the regulator output, with a feedback voltage of 1.215 V to 1.255 V (1.235 V typical). |
| 3 | EN | input | Enable input; drive EN low to shut down the regulator and high to turn it on, with VIL of 0.3 V max and VIH of 1.6 V min. |
| 4 | GND | power_in | Ground. |
| 5 | SW | output | Switching output; connect the power inductor from the input voltage to SW and the external rectifier from SW to the output voltage, with SW to GND rated at 21 V maximum. |
| 6 | VIN | power_in | Main power supply input; supplies the internal circuitry from 1.8 V to 5.5 V for the ADP1612 or 2.5 V to 5.5 V for the ADP1613, and should be bypassed to GND with a 10 µF or greater capacitor placed as close to the device as possible. |
| 7 | FREQ | input | Frequency setting input; connect to GND for 650 kHz, connect to VIN for 1.3 MHz, and note that the part defaults to 650 kHz if FREQ is left floating. |
| 8 | SS | input | Soft-start timing capacitor input; a capacitor from SS to GND brings up the output slowly at power-up and reduces inrush current. |
