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
