JW1531M/JW1531B Parameters Subject to Change Without Notice DESCRIPTION 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. Critical conduction mode operation reduces the switching losses and largely increases the efficiency. JW1531M/JW1531B has multi-protection functions which largely enhance the safety and reliability of the system, including VCC over-voltage protection, VCC UVLO, LED short protectionand over-temperature protection.
