LM25184NGUR

Voltage Regulators - DC DC Switching Regulators

PSR flybackisolated DC/DC65 V MOSFET4.5 V to 42 V inputWSON-8gate drive supply

LM25184NGUR is an integrated primary-side-regulated flyback controller for compact isolated low-power DC/DC rails over a 4.5 V to 42 V input range.

Best for

  • Compact isolated bias supplies
  • IGBT and SiC gate-driver power
  • Industrial isolated DC/DC rails

Avoid if

  • An optocoupler-regulated architecture is mandatory
  • The SW-node voltage cannot be controlled below 65 V
  • Required output power exceeds the validated flyback and thermal design range

Check before use

  • Transformer saturation current and magnetizing inductance
  • Peak SW voltage including ringing
  • Output current capability at minimum input voltage
  • Thermal performance and PCB copper area
