PRODUCT DESCRIPTION

IK2802 is an instant On/Off LED driver for high power LED applications and exploits to enhance its

output characteristics.

IK2802 provides users with 2-channel constant current ports. Users may adjust the output current up

to 360 mA through an external resistor, Rext, which gives users flexibility in controlling the light intensity of

LEDs. Also, users can precisely adjust LED brightness from 0% to 100% via output control with Pulse Width

Modulation. Alternatively, IK2802 provides one-step current adjustment to make 25% of the output current

via enabling the quarter pin (QT) as “Low”.

Additionally, to ensure the system reliability, IK2802 is built with Thermal Protection (TP) function and

thermal pad. The TP function protects IC from over temperature (165°C). Also, the thermal pad enhances

the power dissipation. As a result, a large amount of current can be sunk safely in one package.

APPLICATIONS

 High-flux LED lighting

 Automotive interior lighting
