Monolithic III-nitride power converter

A power management device comprising:

• a monolithic semiconductor die having a first III-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;
• and
• said first III-nitride power semiconductor device and said second III-nitride power semiconductor device electrically isolated from each other by a barrier formed in said monolithic semiconductor die.
