Product Overview

The 750107 is an design kit for 12W LT3748, a high input voltage isolated flyback DC to DC controller including Flyback Transformers for 3.3V, 5V and 12.8V that significantly simplifies the design of an isolated DC to DC converter. No opto isolator, third winding or signal transformer is required for feedback since the output voltage is sensed from the primary side flyback signal. The LT3748 operates in boundary mode, which is a variable frequency current mode control switching scheme, resulting in ±5% typical regulation over the full line, load and temperature range. Boundary mode also permits the use of a smaller transformer compared to equivalent continuous conduction mode designs.
  • Input voltage range 5V to 100V
  • No opto isolator, transformer or third winding required for feedback
  • Drives external N channel power MOSFET
  • Current mode control
  • Boundary mode operation
  • VOUT set with two external resistors
  • Off the shelf transformers
  • Programmable soft start
  • Programmable under voltage lockout
  • Output voltage temperature compensation
