Synchronous step-down DC/DC

Once the mains power supply has been efficiently converted from AC to DC, industrial systems often require further DC/DC conversion to procedure the right sub-system supply voltage. This can be as low as 1.2 V for the logic supply voltage for ICs on a motherboard.

Highlighted components are Nexperia focus products

Products

  • MOSFETs - 30 V, QGD 1.7-13.5 nC, LFPAK / MLPAK
  • Schottky diodes: ≤ 250 mA, SOD523 / DFN1006-2

Design considerations

  • Point of load non-isolated DC-to-DC synchronous buck converter circuit
  • Economical, two-MOSFET design - low QG(tot) & low FOM for best efficiency
  • Step-down of voltage while stepping up current
