The LT ? 3511 is a high voltage monolithic switching regula-
tor specifically designed for the isolated ?yback topology.
No third winding or opto-isolator is required for regula-
tion as the part senses output voltage directly from the
primary-side ?yback 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.
The LT3511 operates from an input voltage range of 4.5V
to 100V and delivers up to 2.5W of isolated output power.
Two external resistors and the transformer turns ratio
easily set the output voltage. Off-the-shelf transformers
are available for several applications. The high level of
