Application Switch-mode power supplies Product status link Chargers and adapters MASTERGAN2 High-voltage PFC, and DC-DC converters Product label Description The MASTERGAN2 is an advanced power system-in-package integrating a gate driver and two enhancement mode GaN transistors in asymmetrical half bridge configuration. The integrated power GaNs have 650 V drain source blocking voltage and R DS(ON) of 150 m and 225 m for Low side and High side respectively, while the high side of the embedded gate driver can be easily supplied by the integrated bootstrap diode. The MASTERGAN2 features UVLO protection on both the lower and upper driving sections, preventing the power switches from operating in low efficiency or dangerous conditions, and the interlocking function avoids cross-conduction conditions. The input pins extended range allows easy interfacing with microcontrollers, DSP units or Hall effect sensors. The MASTERGAN2 operates in the industrial temperature range, -40C to 125C. The device is available in a compact 9x9 mm QFN package.
