Part Number: LMG3100R017

Is the Device useable for parallel connection?

If yes, it is possible to find any documentation regarding parallelization of this GaN device.

Normally it exists a circuit difference between hard / soft switching applications.

Thank you.

Hi Daniel,

Is this for a hard switching or soft switching application?

Hello Kyle,

it is needed for both applications, because its not given in each operation point to work with

soft switching.

Hi Daniel,
The LMG3100R017 devices can be used in parallel in soft switching applications. In hard switching applications we are still doing studies to understand the system requirements for paralleling this device with its integrated gate driver. In a topology that experiences soft switching as well as partial and full hard switching during different regions of operation our current suggestion for the hard switching will be the same as our high voltage devices. To parallel there must be a decoupling inductor between each of the paralleled half bridge's switch nodes.

Best,

Kyle
