JW15310 - JoulWatt

JW15310 BUCK CC/CV Controller

The JW®1531O is a constant voltage constant current controller with high accuracy. JW1531O integrates high voltage power source, and can be supplied from line voltage directly, and auxiliary winding is not needed, which largely simplifies the system. Low standby consumption can be achieved with deep pulse frequency modulation. Critical conduction mode operat.
