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.

The Power factor correction (PFC) function can be acheived with a diode bridge rectifier followed by a single-transistor boost converter using a MOS transistor and SiC rectifier, although while effective, there can be significant power loss in the rectifiers and the MOS transistor. The Totem-pole topology greatly reduces these losses as it avoids the forward voltage loss of the rectifiers and even lower loss can be achieved using discontinuous mode with zero-volt switching. Wide band-gap transistors (i.e. ICeGaN™) are essential for high efficiency in this topology however due to their zero reverse recovery charge.

In lower power, less demanding applications, flyback converters with single power switches can offer an efficient, economical & low-loss solution. This type of converter highlights the extremely low No-Load Power Consumption of ICeGaN®, so crucial for products in this power range. ICeGaN® combines state of the art switching performance with the thermal benefits of integrating a current sense feature - reducing power dissipation and reducing device temperature.
