LT8302 42 VIN Isolated Flyback Converters

Analog Devices' LT8302 is a monolithic micropower isolated flyback converter that operates from an input voltage range of 2.8 V to 42 V and delivers up to 18 W of isolated output power. 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. 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. The converter comes in an 8-SOIC-EP packages with temperature range up to -55°C to +150°C. The LT8302 is perfect for isolated power supplies found in automotive, industrial, and medical applications.
