POWER INTEGRATIONS’ NEW MINE-CAP IC REDUCES VOLUME OF AC-DC CONVERTERS BY UP TO 40%

Power Integrations , the leader in high-voltage integrated circuits for energy-efficient power conversion, announced the MinE-CAP™ IC for high power density, universal input AC-DC converters. By halving the size of the high-voltage bulk electrolytic capacitors required in offline power supplies, this new type of IC enables a reduction in adapter size of up to 40%. The MinE-CAP device also dramatically reduces in-rush current making NTC thermistors unnecessary, increasing system efficiency and reducing heat dissipation.

Comments Power Integrations’ product marketing director, Chris Lee:

The MinE-CAP will be a game-changer for compact chargers and adapters. Electrolytic capacitors are physically large, occupy a significant fraction of the internal volume and often constrain form factor options – particularly minimum thickness – of adapter designs. The MinE-CAP IC allows the designer to use predominantly low voltage rateding capacitors for a large portion of the energy storage, which shrinks the volume of those components linearly with voltage. USB PD has driven a major market push towards small 65 W chargers and many companies have concentrated on increasing switching frequency to reduce the size of the flyback transformer. MinE-CAP provides more volume saving than doubling the switching frequency, while actually increasing system efficiency.
