GENERAL DESCRIPTION

The ADuM5400

1

device is a quad-channel digital isolators with

isoPower™,

an integrated, isolated dc-to-dc converter. Based on

the Analog Devices, Inc.,

iCoupler®

technology, the dc-to-dc

converter provides up to 500 mW of regulated, isolated power at

either 5.0 V from a 5.0 V input supply or 3.3 V from a 3.3 V supply.

This eliminates the need for a separate, isolated dc-to-dc

converter in low power, isolated designs. The

iCoupler

chip scale

transformer technology is used

to isolate the logic signals and the magnetic components of the

dc-to-dc converter. The result is a small form factor, total isolation

solution.

The ADuM5400 isolator provides four independent isolation

channels in a variety of channel configurations and data rates

(see the Ordering Guide for more information).

The contributions of supply current values for all four channels are combined at identical data rates.

The V

ISO

supply current is available for external use when all data rates are below 2 Mbps. At data rates above 2 Mbps, the data I/O channels draw additional current

proportional to the data rate. Additional supply current associated with an individual channel operating at a given data rate can be calculated as described in the

Power Consumption section. The dynamic I/O channel load must be treated as an external load and included in the V

ISO

power budget.

3

The power demands of the quiescent operation of the data channels cannot be separated from the power supply section. Efficiency includes the quiescent power

consumed by the I/O channels as part of the internal power consumption.

4

This current is available for driving external loads at the V

ISO

pin. All channels are simultaneously driven at a maximum data rate of 25 Mbps with full capacitive load

representing the maximum dynamic load conditions. Refer to the Power Consumption section for calculation of available current at less than the maximum data rate.
