PRODUCT DESCRIPTION
IK2816 is an instant On/Off LED driver for lighting applications and exploits to enhance its
output characteristics. At IK2816 output stage, sixteen regulated current ports are designed to
provide uniform and constant current sinks for driving LEDs within a large range of VF
variations.
IK2816 provides users 16-channel constant current ports to match LEDs with equal current.
Users may adjust the output current from 5 mA to 60 mA through an external resistor, Rext,
which gives users flexibility in controlling the light intensity of LEDs. In addition, users can
precisely adjust LED brightness from 0% to 100% via output enable
with Pulse Width Modulation.
Additionally, to ensure the system reliability, IK2816 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
handled safely in one package.
APPLICATIONS
 Automotive interior lighting
 Channel letter
 Decoration lighting
