IK402U

TECHNICAL DATA CONSTANT CURRENT LINEAR LED DRIVER IK402U DESCRIPTION IK402U is a high-stable current source IC designed to be used as a constant current LED driver. Application of a constant current source provides continuous brightness of LED light and long LED life time. Moreover, a constant current source provides an over-temperature protection to LED. FEATURE  High-stability output current  Low dropout voltage  Easy adjustable output current  Negative thermal coefficient of output current  Small overall dimensions, possible chip mount in a single package with LED  Low cost, no external elements, simple use  LED drive current of 22 mA  Supply voltage up to 42 V  Easy paralleling of drivers to increase current  Low voltage overhead of 1.2 V  High current accuracy at supply voltage variation  No EMI  ESD Rating: Human Body Model 2000V  Reduced output current at higher temperatures – negative thermal coefficient of - 0.1 %/K APPLICATION  Channel letters for advertising, LED strips for decorative lighting  Aircraft, train, ship illumination  Retrofits for general lighting, white goods like refrigerator lighting  Medical lighting  Automotive applications like CHMSL and rear combination lights SOT-23-6 1 November 2014, Rev. 01 IK402U MAXIMUM RATINGS Parameter Supply voltage Output voltage Reverse voltage between all terminals Junction Temperature Symbol VS VOUT VR Tj Pmax= (VS – VOUT)  IOUT is determined by the condition Tj 150°C Value 42 18.6 0.5...
