VAS1086 is a wide input range constant current LED driver provides cost-effective solution for advertising light boxes， landscape lighting and other LED illumination application. For most applications， VAS1086 only need one current setting resistor from SET to GND， and one ceramic bypass capacitor from VIN to GND， no aluminum capacitor， Schottky diode or inductor needed. For high current application， several VAS1086 can be connected in parallel to obtain high power output. VAS1086 make use of an external power resistor to reduce chip power dissipation when poor power supply is used. Meanwhile ， the VAS1086 will automatically reduce linearly the output current when the die temperature reached 120°C， this method avoid LED bar blinking. Over temperature protection is also be integrated. VAS1086 is available with SOP8-e package.
