HI9300

Component

synchronous buck8 V to 120 Vexternal MOSFETESSOP-10cycle-by-cycle overcurrent protection

Hi9300 is an external-MOSFET synchronous buck controller for high-voltage 8 V to 120 V input rails and adjustable 0.9 V to 48 V outputs.

Best for

  • High-voltage non-isolated buck converters
  • Industrial control power rails
  • Telecom bus conversion

Avoid if

  • A fully integrated regulator is required
  • Input voltage can exceed the specified 120 V operating range
  • Compliance or lifecycle documentation is mandatory but unavailable

Check before use

  • Set output voltage using the 0.843 V feedback reference
  • Set cycle-by-cycle current limit with the CS network
  • Keep high-current switching loops short and wide on the PCB
