Product Overview

The LT8301IS5#TRMPBF is a micropower no-opto-isolated Flyback Converter with 65V/1.2A 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 a single external resistor. Internal compensation and soft-start further reduce external component count. 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 DMOS power switch is integrated along with all high voltage circuitry and control logic. It operates from an input voltage range of 2.7 to 42V and can deliver up to 6W of isolated output power. The high level of integration and the use of boundary and low ripple burst modes result in a simple to use, low component count and high efficiency application solution for isolated power delivery.
  • Boundary mode operation at heavy load
  • Low-ripple Burst Mode® operation at light load
  • VOUT set with a single external resistor
  • Accurate EN/UVLO threshold and hysteresis
  • Internal compensation and soft-start
  • Output short-circuit protection
  • Minimum load <0.5% (typical) of full output
