JW18287A
DESCRIPTION
JW®18287A/JW18287B/JW18287C (JW18287X) is a non-isolated PWM dimmable constant current LED regulator with high current accuracy which applies to single stage step-down LED drivers. JW18287X is supplied from the line directly without auxiliary winding or external capacitor, which can lower the system BOM cost. Patented algorithms ensure good current accuracy and excellent line/load regulations.
With unique sampling techniques, JW18287X has multi-protection functions which can largely enhance the safety and reliability of the system, including LED short protection, LED open protection and over-temperature protection.
FEATURES
• No auxiliary winding
• Excellent line/load regulation
• Internal PWM to analog dimming
• High efficiency
• LED short protection
• LED open protection
• SOP8 package
