ADuM5200

1 Each voltage is relative to its respective ground.
2 The VISO provides current for dc and dynamic loads on the Side 2 input/output channels. This current must be included when determining the total VISO supply current.
3 VDDI and VDDO refer to the supply voltages on the input and output sides of a given channel, respectively. See the PCB Layout section.
4 See Figure 5 for maximum rated current values for various temperatures.
5 Refers to common-mode transients across the insulation barrier. Common-mode transients exceeding the absolute maximum ratings may cause latch-up or permanent damage.

The ADuM520x are dual 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 with 5.0 V input and 5.0 V output voltage, or 200 mW of power with 3.3 V input and 3.3 V output voltage. This eliminates the need for a separate isolated dc-to-dc converter in low power isolated designs. The Analog Devices chip scale transformer iCoupler technology is used for the isolation of the logic signals as well as for the dc-to-dc converter. The result is a small form factor, total isolation solution.

ADuM520x units can be used in combination with the ADuM5401, ADuM5402, ADuM5403, ADuM5404, and ADuM5000 with isoPower® to achieve higher output power levels and greater channel counts (see the Increasing Available Power section).

The ADuM520x isolators provide two independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide for options).

isoPower uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. Refer to the  ADuM520x application note for details on board layout recommendations.
