A DC-DC conversion provides a low voltage output, current regulation, and safety isolation. The LLC configuration achieves very high efficiency because it can operate in zero-volt and zero-current switching mode, which greatly reduces losses. High frequency operation, enabled by CGD GaN technology ensures also best in class power density.

After a PFC stage, DC-DC conversion provides low voltage output, current regulation, and safety isolation suitable for operating the load. The LLC configuration achieves very high efficiency because it can operate in zero-volt and zero-current switching mode, which greatly reduces losses. High frequency operation, enabled by CGD GaN technology means small size as well.

In lower power, less demanding applications, flyback converters with single power switches can offer economical solutions. If some flicker is acceptable, then power factor correction and DC-DC conversion can be combined in one stage. Power losses can be minimised by using quasi-resonant operation. Active clamp Flyback for optimised losses requires an additional low power switch but is valuable for best performance. High frequency operation, enabled by ICeGaN® achieves all of this as well as compact overall size.
