Integrated DC/DC Converter, 50 mW

ADuM5240/ADuM5241/ADuM5242

GENERAL DESCRIPTION

The ADuM524x

integrated DC/DC converter. Based on Analog Devices’

iCoupler® technology, the DC/DC converter provides up to

50 mW of regulated, isolated power at +5V. This eliminates the

need for a separate isolated DC/DC converter in low-power

isolated designs. Analog Devices’ chip-scale transformer

iCoupler

signals as well as for the DC/DC converter. The result is a small

form-factor total-isolation solution.

ADuM524x units may be used in combination or with other

iCoupler products to achieve greater channel counts.

The ADuM524x isolators provide two independent isolation

channels in a variety of channel configurations and data rates

(see Ordering Guide) operating off a 5V input supply.
