LM5117PMHX/NOPB is a 65 V synchronous buck controller for external MOSFET power stages, with programmable frequency, current-mode control, protection functions, and analog output-current monitoring.

Best for

  • Wide-input non-isolated buck converters
  • External MOSFET power stages requiring current-mode control
  • Applications needing average output-current monitoring

Avoid if

  • A fully integrated regulator with internal power switches is required
  • A verified current lifecycle or supply status is mandatory

Check before use

  • Input transient margin at VIN and SW
  • Maximum-duty-cycle requirement
  • MOSFET gate charge and bootstrap capacitor sizing
  • Current-sense and short-circuit thermal limits
