The ceramic nonhermetic hybrid package with side-brazed pins contains a transformer-coupled DC/ DC converter and a capacitor-coupled signal channel. Extra power is available on the isolated output side for driving external loads. The converter is protected from shorts to ground with an internal current limit, and the soft-start feature limits the initial currents from the power source. Multiple-channel synchronization can be acplished by applying a TTL clock signal to paralleled Sync pins. The Enable control is used to turn off transformer drive while keeping the signal channel modulator active. This feature provides a convenient way to reduce quiescent current for low power applications. The wide barrier pin spacing and internal insulation allow for the generous 1500Vrms continuous rating. Reliability is assured by 100% barrier breakdown testing that conforms to UL1244 test methods. Low barrier capacitance minimizes AC leakage currents. These specifications and built-in features make the ISO113 easy to use, and provides for pact PC board layout. +VC Sense V OUT Gnd 2 - VC +VCC2 Oscillators, Driver Rectifiers, Filters Ps Gnd - VCC2 - Ground if not used APPLICATIONS q q q q q 4m A TO 20m A V/I CONVERTERS MOTOR AND VALVE CONTROLLERS ISOLATED RECORDER OUTPUTS MEDICAL INSTRUMENTATION OUTPUTS GAS ANALYZERS +VCC1 V IN - VCC1 1 Sync- Enable Gnd 1 Sync Duty Cycle Modulator Duty Cycle Demodulator International Airport Industrial Park - Mailing Address: PO Box 11400, Tucson, AZ...
