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 260mA, 150V DMOS power switch is integrated along with all high voltage circuitry and control logic into a 5-lead ThinSOT™ package.
The LT8300 operates from an input voltages range of 6V to 100V and can deliver up to 2W 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.
