General Description

This GaNSense™ HFQR/CCM controller integrates a high performance eMode GaNSense Power FET together with an Flyback controller to achieve unprecedented high-frequency and high-efficiency operation for smallest size mobile charger and adapter solutions.

The GaNSense Power FET includes loss-less current sensing, ultra-low gate charge, low output charge,700V continuous and 800V transient voltage ratings to provide excellent performance and robustness.

The HFQR Flyback controller enables high frequency operation, wide VDD range, high-voltage start-up, and multi-mode operation.
