TOPSwitch-JXflybackoff-line switcher725 V MOSFETeSIP-7C

TOP271EG is an integrated high-voltage flyback switcher for off-line power supplies, combining a 725 V MOSFET with PWM control and protection functions.

Best for

  • Isolated off-line flyback converters
  • AC adapters and standby supplies
  • Power supplies requiring integrated protection

Avoid if

  • The design requires a topology other than an integrated flyback switcher
  • The required power or thermal conditions exceed the stated package capability

Check before use

  • Transformer and reflected-voltage design
  • Drain-voltage clamp performance
  • PCB heat sinking and junction temperature
  • Required switching-frequency configuration
