Key Document


The PMP11186 reference design is a non-isolated Push-Pull converter that operates from 6V - 16Vin and supplies +/- 25V@5A out (250W max).  This design operates at 200KHz with a peak efficiency of 88% (Vin = 12V).

  • 250W peak output power at 6V input
  • 86% full load and 88% half load efficiency
  • Excellent output regulation with balanced differential loading
