Product Overview

The LT8302IS8E#PBF is a monolithic micropower isolated Flyback Converter with 65V/3.6A switch. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no third winding or opto-isolator for regulation. The output voltage is programmed with two external resistors and a third optional temperature compensation resistor. Boundary mode operation provides a small magnetic solution with excellent load regulation. Low ripple burst mode operation maintains high efficiency at light load while minimizing the output voltage ripple. A 3.6A, 65V DMOS power switch is integrated along with all the high voltage circuitry and control logic. The LT8302 operates from an input voltage range of 2.8 to 42V and delivers up to 18W of isolated output power.
  • Quasi-resonant boundary mode operation at heavy load
  • Minimum load <0.5% (typical) of full output
  • No transformer third winding or opto-isolator required for output voltage regulation
  • Accurate EN/UVLO threshold and hysteresis
  • Internal compensation and soft-start
  • Temperature compensation for output diode
  • Output short-circuit protection
