LMR51420XFDDCR

Voltage Regulators - DC DC Switching Regulators

Buck ConverterSynchronousIndustrialFPWM

The LMR51420XFDDCR is a 2-A, 36-V synchronous buck converter in a SOT-23 package, optimized for industrial applications with a 500-kHz fixed switching frequency and FPWM mode.

Best for

  • Industrial power supplies
  • Motor drives
  • Building automation

Avoid if

  • Extremely space-constrained designs requiring ultra-low light-load power consumption (consider PFM version instead)

Check before use

  • Thermal dissipation requirements for the SOT-23 package at full 2-A load
