    LT3575
    Isolated Flyback Converter
    without an Opto-Coupler
    FEATURES DESCRIPTION n The LT®3575 is a monolithic switching regulator specifically designed for the isolated flyback topology. No third
    winding or optoisolator is required for regulation. The
    part senses the isolated output voltage directly from the
    primary side flyback waveform. A 2.5A, 60V NPN power
    switch is integrated along with all control logic into a
    16-lead TSSOP package. n 3V to 40V Input Voltage Range
    2.5A, 60V Integrated NPN Power Switch
    Boundary Mode Operation
    No Transformer Third Winding or
    Optoisolator Required for Regulation
    Improved Primary-Side Winding Feedback
    Load Regulation
    VOUT Set with Two External Resistors
    BIAS Pin for Internal Bias Supply and Power

    Programmable Soft-Start
    Programmable Power Switch Current Limit
    Thermally Enhanced 16-Lead TSSOP The LT3575 operates with input supply voltages from
    3V to 40V, and can deliver output power up to 14W with
    no external power switch.The LT3575 utilizes boundary ...

    Micropower Isolated Flyback Converter with Input Voltage Range from 6V to 100V

    Micropower Isolated Flyback Converter with Input Voltage
    Range from 6V to 100V
    Design Note 509
    Zhongming Ye
    Introduction
    Flyback converters are widely used in isolated DC/DC
    applications because of their relative simplicity and
    low cost compared to alternative isolated topologies. Even so, designing a traditional flyback is not
    easy—the transformer requires careful design, and
    loop compensation is complicated by the well known
    right-half plane (RHP) zero and the propagation delay
    of the opto-coupler.
    Linear Technology’s no-opto flyback converters, such
    as the LT В® 3573, LT3574, LT3575, LT3511 and LT3512,
    simplify the design of flyback converters by incorporating a primary-side sensing scheme and running the
    converter in boundary mode. The LT8300 high voltage
    monolithic isolated flyback converter further simplifies
    flyback design by integrating a 260mA, 150V DMOS
    power switch, an internal compensation network and a
    soft-start capacitor. The LT8300 operates with input supply voltages from 6V to 100V and delivers output power
    of up to 2W with as few as five external components.
    The LT8300 operates in boundary mode and offers low
    ripple Burst ModeВ® operation, enabling the design of ...

    Monolithic No-Opto Isolated Flyback Converter Provides
    Versatile Solution
    Design Note 525
    George Qian
    Introduction
    Traditionally, isolated power supplies use an optocoupler in the feedback loop to transfer regulation
    information across the isolation barrier. Unfortunately,
    an opto-coupler’s gain characteristic varies widely over
    temperature and lifetime, increasing the difficulty of
    power supply loop compensation.
    Linear Technology’s line of no-opto flyback converters,
    such as the LTВ®3573, LT3574, LT3575, LT3511, LT3512
    and LT8300, simplify flyback design by incorporating
    a primary-side sensing scheme, thereby eliminating
    the need for an opto-isolator.
    The LT8302 monolithic no-opto flyback converter
    has an integrated 65V/3.6A DMOS power switch with
    internal loop compensation and soft-start. The LT8302
    can operate from an input voltage as low as 2.8V to
    42V, and deliver output power up to 18W. It offers
    low ripple Burst Mode В® operation at light loads, providing low standby power loss, and features a low
    component count.
