Dramatically Simplifies CV/CC Converters

• Eliminates optocoupler and all secondary CV/CC control circuitry

• Eliminates all control loop compensation circuitry

Advanced Performance Features

• Dynamic base drive technology provides flexibility in choice of BJT

transistor by dynamically optimizing BJT switching characteristics
