DESCRIPTION

The LT?8306 is a micropower isolated flyback

controller in a 6-lead ThinSOT? package. By sampling

the isolated output voltage directly from the primaryside

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.
