60V Low IQNo-Opto Isolated Flyback Controller

Description

The LT8306 is a micropower isolated flyback controller in a 6-lead ThinSOT™package. 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. The LT8306 drives a low side N-channel power MOSFET with 8V gate drive.The LT8306 has a wide input voltage range of 4.5V to 60V. 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.APPLICATIONSIsolated Telecom, Automotive, Industrial, Medical Power SuppliesIsolated Auxiliary/Housekeeping Power Supplies
