... APPLICATIONS INFORMATION THEORY OF OPERATION The dc-to-dc converter section of the ADuM5401/ADuM5402/ ADuM5403/ADuM5404 works on principles that are common to most modern power supplies secondary side controller architecture with isolated pulse-width modulation (PWM) feed- back. V power is supplied to an oscillating circuit that switches DD1 current into a chip-scale air core transformer. Power transferred to the secondary side is rectified and regulated to either 3 ...

N is the number of turns in the receiving coil the radius of the n n Given the geometry of the receiving coil in the ADuM5401/ ADuM5402/ADuM5403/ADuM5404, and an imposed require- ment that the induced voltage be, at most, 50% of the 0.5 V margin at the decoder, a maximum allowable magnetic field is calculated as shown in Figure 25 ...

... The preceding magnetic flux density values correspond to specific current magnitudes at given distances from the ADuM5401/ ADuM5402/ADuM5403/ADuM5404 transformers. Figure 26 expresses these allowable current magnitudes as a function of frequency for selected distances. As shown in Figure 26, the ADuM5401/ ADuM5402/ADuM5403/ADuM5404 are extremely immune and can be affected only by extremely large currents operated at high frequency very close to the compo- nent ...

... Operation at working voltages higher than the service life voltage listed leads to premature insulation failure. The insulation lifetime of the ADuM5401/ADuM5402/ ADuM5403/ ADuM5404 depends on the voltage waveform type imposed across the isolation barrier. The iCoupler insulation structure degrades at different rates, depending on whether the waveform is bipolar ac, unipolar ac ...
