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.
