It uses an air core magnetic structure to couple power from the input of each channel to the receiver in the channel’s output. The inputs are driven from a voltage driver source and require no series current limiting resistors; the outputs are open-collector, and perform a logical inversion of the input signal. The Digital Isolator should be physically placed near its associated powertrain, across the isolation barrier of PCB. The maximum recommended trace length between any of the Digital Isolator (primary side) transmit and receive channels and the primary referenced control pins of the powertrain is 6”. Digital Isolators are an effective alternative to optocouplers. Their low profile is valuable in high density power systems, their channel count is optimized for Vicor BCM and DCM converters. Digital Isolators offer improved system reliability as there is no LED emitter to degrade with use, and no optical barrier to degrade with time. All three channels have the same internal structure and nominal performance, but are grouped in a 2 transmit/ 1 receive configuration so that data can be transferred to and from the power converters in the system. A Digital Isolator channel performs a logical inversion on the data as it is transferred to the open collector output. The transmit and receive ports on each side of the isolation boundary have a common low side, to optimize package pin utilization. The maximum recommended trace length between any of the Digital Isolator secondary referenced transmit and receive channels and the system Digital Supervisor i/o pin is 18”. All traces should be 8 mil wide, ½ oz. copper, or equivalent for series resistance purposes. While strict impedance control is not required for proper operation, the three channel signals on each side of the Digital Isolator should be routed in such a way as to minimize the likelihood of interference or stray noise pickup. A stripline or microstrip structure is recommended, with the common pin run as the shield or reference.
