异步降压LED汽车照明驱动VAS1350

VAS1086是一种宽输入范围恒流电路LED驱动器为广告灯箱、景观照明其他LED照明应用。对大多数人来说应用，VAS1086只需要一个电流设置电阻从SET到GND，一个从VIN到GND的陶瓷旁路电容器，无铝电容器，肖特基二极管或电感需要。对于大电流应用，几个VAS1086可并联连接以获得高功率输出。VAS1086利用外部电源电阻，以减少芯片功耗时电源不良。与此同时VAS1086将自动线性减少模具温度达到时的输出电流120°C时，此方法可避免LED指示灯闪烁。还应提供超温保护
VAS1086封装SOP8-e

General Description VAS1350 is a PFM mode boost LED driver with external power MOSFET. By adjusting external sense resistor, VAS1350 can deliver up to several amperes output current and suitable for high power LED array applications. VAS1350 operates from a 5V to hundreds of voltages input range. Its overvoltage protection can avoid damage to circuit of open load and a dedicated analog input (ADJ) enables a wide range of analog dimming from 0.5V to 2.4V. VAS1350 provide excellent protection functions, such as MOSFET over current protection, ROVP short to ground protection, UVLO and over heat protection, LED open protection. VAS1350 is available with SOP8 package
