Product Details

Demonstration circuit 1825A is an isolated flyback converter featuring the LT8300. This demo circuit outputs 5.0V, and maintains tight regulation with a load current from ~1mA to 250mA and over an input from 22V to 75V, with a nominal 48V. The output current capability increases with the input voltage. The DC1825A needs a very small minimum load (~1mA) to regulate the output voltage, thanks to the accurate current limit capability and ultra low switching frequency of the LT8300 at very light load. The standby input current of the demo circuit is less than 400μA (typical) because of the low quiescent current design of the IC and very small minimum load requirement.
