LM5088MH-2/NOPB is a high-voltage asynchronous buck controller for 4.5 V to 75 V inputs, using an external high-side N-channel MOSFET and programmable switching frequency.

Best for

  • High-input-voltage asynchronous buck converters
  • Industrial DC/DC bias supplies
  • Automotive infotainment and accessory power

Avoid if

  • A fully integrated power stage is required
  • A synchronous rectifier topology is required
  • Input transients can exceed the device voltage rating without protection

Check before use

  • Keep VIN below 75 V during operation and below 76 V absolute maximum including ringing
  • Use a Schottky recirculating diode
  • Kelvin-connect CS and CSG to the sense resistor
  • Connect the exposed pad to ground copper for thermal performance
