LT8301 / LT8302 Isolated Flyback Converters

Analog Devices Inc. LT8301 / LT8302 Isolated Flyback Converters sample the isolated output voltage directly from the primary-side flyback waveform. The LT8301 / LT8302 from Analog Devices 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.
