Navitas Semiconductor - World's First & Fastest GaN Power IC
Contact

The GaNSense Control family combines next-gen gallium nitride (GaN) power with high-frequency control functionality. Unlike competing systems, GaNSense Control has all the benefits of the monolithically-integrated GaN power FET and GaN drive, plus control and protection circuits in a single surface-mount package, for high-density charger, adapter and auxiliary power applications.

Easy-to-Use, Flexible, Efficient

A comprehensive, easy-to-use portfolio of co-packaged and standalone solutions offers ultimate flexibility to the power designer. NV958x high-frequency quasi-resonant (HFQR) flyback controllers with GaNSense power ICs support QR, DCM, CCM and multiple-frequency, hybrid-mode operations. A choice of frequency ranging from 82 to 225 kHz provides flexible design for both planar or wire-wound transformers, offering highly-efficient, and most-compact charger solutions. On the secondary side, NV97xx synchronous rectifier (SR) controllers with power FETs provide maximum efficiency at any load condition compared to conventional rectifiers.

World-Class Performance

GaNSense Control enables the highest-frequency operation to minimize system size and weight. Integrated features such as loss-less current sensing, high-voltage start-up, and elimination of VDD inductor reduce component count and increase system efficiency. With transient voltage breakdown up to 800 V and no PCB hotspots, Navitas’ GaNSense Control delivers best-in-class efficiency in the smallest form-factor.
