DC1825A

DC1825A is a LT8300 100VIN micropower isolated flyback converter with 150V/260mA switch demonstration board. Demonstration circuit 1825A is an isolated flyback converter featuring the LT®8300. This demo circuit outputs 5V 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. TheLT8300 is a simple-to-use high voltage monolithic isolated flyback converter. No third winding or opto-isolator is required for regulation.

• Typical switching frequency if 330KHz at VIN = 48V, IOUT = 250mA, TA = 25°C
• Efficiency is 80% at VIN = 48V, IOUT = 250mA, TA = 25°C
