Voltage Regulators - DC DC Switching Regulators

buck regulator5 V fixed output0.5 ASOIC-1452 kHznon-synchronous

LM2574MX-5.0/NOPB is a fixed 5 V, 0.5 A non-synchronous buck regulator for simple low-current step-down supplies. It uses an external inductor, catch diode, input capacitor, and output capacitor.

Best for

  • Simple 5 V buck supplies up to 0.5 A
  • Preregulators for linear regulators
  • Low-frequency board-level switching supplies

Avoid if

  • Higher output-current designs
  • Applications requiring a synchronous converter
  • Compact designs requiring high switching frequency

Check before use

  • Input voltage including transients
  • Inductor saturation-current rating
  • Catch diode current and reverse-voltage rating
  • Output-capacitor ESR and ripple-current rating
  • PCB thermal layout
