Spec.

Various protection functions
Includes multiple built-in protection functions to allow for safe use including capacitive mode protection, input monitoring, pulse-by-pulse overcurrent protection, and more.
Achieve high efficiency through all load ranges
Including Shindengen’s proprietary asymmetric control makes it possible to improve efficiency during light loads which LLC current resonance circuits do not handle well, making it possible to achieve high efficiency through all load ranges.

Achieves downsize transformers and miniaturization of the entire power supply
Compatible with control up to a maximum of 500kHz (under normal operation), which makes it possible to downsize transformers, thus achieves miniaturization of the entire power supply.

Reduced excitation current and improved light load efficiency
Realizes asymmetric control which doubles low side ON width, which makes it possible to work towards reducing excitation current thereby improving efficiency during light loads. Asymmetric control improves MOSFET dissipation by approximately 65% (at 10W)
