JW1531B Overview
The JW®1531B/JW1531M is a constant voltage constant currentdriver with high accuracy. JW1531M/JW1531B 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.
