DC DC Switching Controllers

PSR flyback100 V inputAEC-Q100automotiveisolated DC/DCHTSSOP-14

LM5185QPWPRQ1 is a 100 V-input automotive PSR flyback controller for isolated auxiliary rails where optocoupler-free regulation and low EMI are required.

Best for

  • Automotive isolated auxiliary supplies
  • IGBT and SiC gate-drive bias supplies
  • Wide-input industrial flyback converters

Avoid if

  • Applications requiring an integrated power MOSFET
  • Non-isolated buck conversion

Check before use

  • Confirm maximum input transient voltage stays within the system design margin.
  • Validate output regulation across load, temperature and diode forward-voltage variation.
  • Follow high di/dt layout guidance around VIN, transformer, MOSFET, current sensing and clamp circuitry.
