Product Overview

DC1860B is a demonstration circuit featuring the LT3748 isolated flyback converter. This demo circuit is designed for Power Sourcing Equipment (PSE) applications with a 52.5V output from a 10V to 15V DC input, with nominal input voltage of 12V. The output current is from 0mA to 700mA and is capable of a maximum short period overload current of 900mA. This demo circuit can also be easily modified for different PSE applications with some predesigned transformers. The LT3748 is a high input voltage isolated flyback controller operating with input supply voltages from 5V to 100V and 1.9A average gate drive source and sink current. The LT3748 utilizes boundary mode operation to provide a high efficiency, small size solution with improved regulation. The part senses the isolated output voltage directly from the primary side flyback waveform during the off time of the power switch. No third winding, opto-coupler, or signal transformer is required for regulation.
  • 150mV typ output voltage ripple (Peak to Peak) at VIN = 10V to 15V, IOUT = 0 to 700mA
  • 87.8% typ efficiency at VIN = 13.2V, IOUT = 700mA
