... APPLICATIONS INFORMATION THEORY OF OPERATION The dc-to-dc converter section of the ADuM5401W/ADuM5402W/ ADuM5403W works on principles that are common to most modern power supplies secondary side controller architecture with isolated pulse-width modulation (PWM) feedback. V power is supplied to an oscillating circuit that switches current into a chip-scale air core transformer. Power transferred to the secondary side is rectified and regulated ...

... ADuM5401W/ ADuM5402W/ADuM5403W transformers. Figure 23 expresses these allowable current magnitudes as a function of frequency for selected distances. As shown in Figure 23, the ADuM5401W/ ADuM5402W/ADuM5403W are extremely immune and can be affected only by extremely large currents operated at high frequency very close to the component. For the 1 MHz example, a 0.5 kA current placed 5 mm away from the ADuM5401W/ADuM5402W/ ADuM5403W is required to affect component operation ...
