buck regulatoradjustable output3 A60 V inputDDPAKnon-synchronous

LM2576HVS-ADJ/NOPB is a 3 A adjustable non-synchronous buck regulator for wide-input supplies up to 60 V recommended input.

Best for

  • Wide-input industrial buck supplies
  • 3 A loads where low switching frequency is acceptable
  • Applications using through-hole or large passive power components

Avoid if

  • Very small solution size is required
  • High switching frequency is needed to reduce magnetics
  • A synchronous converter is required for maximum efficiency

Check before use

  • Validate inductor saturation and peak-current margin
  • Use a suitably rated Schottky or soft-recovery catch diode
  • Keep input-capacitor and diode switching loops short
  • Calculate junction temperature for worst-case load and ambient temperature
