Beschreibung

This small form factor power supply provides bias power to isolated silicon carbide (SiC) or gallium nitride (GaN) MOSFET gate drivers when extremely high dV/dT on the secondary side is expected, such as wideband gap switches. The board accepts 24V input and supplies 12V at 200mA. The resonant inductor-inductor-capacitor (LLC) topology, combined to low primary to secondary winding capacitance, makes this converter an option for low-noise and high common-mode transient immunity (CMTI) applications, while reducing common-mode current injection through the transformer. Even though this isolated LLC converter works in open-loop, the output voltage keeps tracking VIN and has very low variation versus load current.
