Abstract
First and second power transistors collectors of which are connected with each other, other first and second loss sharing transistors connected to bases of the first and second power transistors at collectors thereof, respectively. A first driver transistor is connected to the emitter of the first loss sharing transistor at the collector thereof, and a second driver transistor is connected to the emitter of the second loss sharing transistor at the collector thereof. The base of each of the loss sharing transistors is applied with a constant voltage at the base thereof.
