Voltage Regulators - DC DC Switching Regulators

synchronous buck42 V input0.75 Aadjustable regulatorPowerPAD HTSSOP

LM3103MHX/NOPB is a 42 V synchronous buck regulator for adjustable low-voltage rails up to 0.75 A, with integrated MOSFETs and a 16-pin PowerPAD HTSSOP package.

Best for

  • Low-power wide-input industrial buck rails
  • Embedded-system point-of-load supplies
  • 12 V or 24 V input power conversion

Avoid if

  • Applications requiring output current substantially above 0.75 A
  • Designs unable to accommodate careful thermal and switching-node PCB layout

Check before use

  • Validate duty-cycle limits at minimum input voltage
  • Verify inductor peak and saturation current
  • Connect the exposed thermal pad to the ground plane
