LT3573IMSE#TRPBF

Voltage Regulators - DC DC Switching Regulators

IsolatedFlybackSwitching Regulator

The LT3573 is an isolated flyback switching regulator that eliminates the need for opto-isolators or third transformer windings by sensing output voltage from the primary side.

Best for

  • Isolated power supplies
  • Space-constrained designs

Avoid if

  • Non-isolated applications where simpler buck/boost converters suffice

Check before use

  • Transformer turns ratio and leakage inductance
