USB Power Supply 10V/1A with BJT in EmitterSwitchingTechnique. In a commercial USB power supply 10V/1A the BJT switching transistor was replaced by an EmitterSwitchingTechnique stage. The advantages are nearly a doubling of the dielectric strength. This leads to highest reliability at lowest price. Fig. left top: Modified Power Supply original Transistor.
