1 / 13 page TECHNICAL DATA 1 2011, February Ver. 03 Small Outline Package SOP8 HIGH-POWER LED DRIVER FEATURES 2 constant-current output channels Constant output current invariant to load voltage change Maximum output constant current per channel: 360 mA Thermal protection and flag Output current adjusted through an external resis- tor Schmitt trigger input 5V supply voltage Package type: Pb-free package with thermal pad ORDERING INFORMATION Device Operating Tempera- ture Range Package Shipping IK2802DT ТА = - 40 ... + 85 С SOP-8 Tape& Reel Current Accuracy Conditions Between Channels Between ICs <±3% <±6% IOUT = 40mA ~ 360 mA @ VDS= 0.6V 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.
