A New Approach to Circuit Breaker Design Using Silicon Carbide Switches - Nov 21
Mechanical circuit breakers can be low cost with minimal losses, but they operate slowly and wear out. Solid state versions overcome the problems and are becoming increasing viable as replacements at...

Reference design helps GaN ICs reduce size of power adapters

At over 21W/in3 and at over 95% efficiency, the NVE021A reference design is more than two times smaller than typical commercial designs, according to the company, and 40% smaller than the current best-in-class option.

The design can be adapted over a power range of 85 to 500W, to enable converters that address thin LED TVs, fast-charging laptop adapters, high-density gaming systems, all-in-one PCs and any other systems seeking high-density or high efficiency power.

The GaN power ICs enable high-frequency switching to shrink passive components. Soft-switching critical-conduction mode (CrCM) power factor correction and LLC DC/DC stages operate at up to 300kHz (600kHz during start-up, burst mode). This, says the company, is the fastest-possible speed provided by off-the-shelf controller ICs available today.

The reference design (150W, AC to 12V DC) is immediately available, and includes a user guide / test report with all schematic and layout design files, and bill of materials.
