Reduces Volume of Input Bulk Capacitors by up to 50%

The MIN1072M MinE-CAP™ IC from POWER INTEGRATIONS dramatically shrinks the size of input bulk capacitors without compromising output ripple, operating efficiency or requiring redesign of the transformer.

When compared to traditional techniques such as very high switching frequency operation, MinE-CAP™ achieves the same or greater overall power supply size reduction whilst avoiding the challenges of complex EMI filtering and the increased transformer/clamp dissipation associated with very high frequency designs.

MinE-CAP™ also precisely manages inrush current at AC turn-on, eliminating the need for dissipative NTCs or large slow-blow fuses.
