    Monolithic High Voltage
    Isolated Flyback Converter
    Features Description n n The LT3512 is a high voltage monolithic switching regulator specifically designed for the isolated пђВyback topology.
    No third winding or opto-isolator is required for regulation as the part senses output voltage directly from the
    primary-side пђВyback waveform. The device integrates a
    420mA, 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
    Internal 420mA, 150V Power Switch
    Boundary Mode Operation
    No Transformer Third Winding or
    Opto-Isolator Required for Regulatio Improved Primary-Side Winding Feedback

    OUT Set with Two External Resistors
    n BIAS Pin for Internal Bias Supply and Power
    Switch Driver
    n No External Start-Up Resistor
    n 16-Lead MSOP Package The LT3512 operates from an input voltage range of 4.5V
    to 100V and delivers up to 4.5W 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 ...
