ADP1613ARMZ-R7

Analog Devices · DC-DC Converters · MSOP-8

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.
