LT3511
Monolithic High Voltage
Isolated Flyback Converter
FEATURES DESCRIPTION n The LT®3511 is a high voltage monolithic switching regulator specifically designed for the isolated flyback topology.
No third winding or opto-isolator is required for regulation as the part senses output voltage directly from the
primary-side flyback waveform. The device integrates a
240mA, 150V power switch, high voltage circuitry, and
control into a high voltage 16-lead MSOP package with
four leads removed. 4.5V to 100V Input Voltage Range
