DESCRIPTION

TheJW1969A/JW1969B/JW1969C/JW1969D/ JW1969E/JW1969BC/JW1969DC/JW1969EC

(JW1969Cseries) is a constant current LED regulator which apply to single stage step-down power factor corrected LED drivers.

JW1969Cseries integrates high voltage power source, and can be supplied by line voltage directly, auxiliary winding and vcc capacitor are

not needed. JoulWatt Confidential

Patented current sensing and digital

compensation technics ensure a unit power factor and high accuracy output current. The critical conduction mode operation reduces the switching losses and increases the efficiency

Jw1969Cseries has multi-protection functions which largely enhance the safety and reliability of the system including LED open protectionLED short protection and over-temperature protection.

FEATURES

No auxiliary winding and VCC capacitor Supplied from line voltage directly
