Monolithic group III-V power converter

A power management device comprising:

• a monolithic semiconductor die integrated on a silicon substrate;
• said monolithic semiconductor die having a first HI-nitride power semiconductor device and a second III-nitride power semiconductor device coupled to said first III-nitride power semiconductor device in a half-bridge configuration;
• said half-bridge configuration including a first driver half-bridge arrangement coupled to said first III-nitride power semiconductor device, and a second driver half-bridge arrangement coupled to said second III-nitride power semiconductor device.
