高效的白光LED驱动电路设计

怎么看不到电路图啊

不知道大家作过试验了没有，在作灯饰的时候即使选用很好的LED作材料，总是会出现死灯

hao

我對這個有興趣

2A(AC 85-265V)LED驱动IC-AMC7160介绍及应用应用方案(照明)AMC7160 is a PWM power LED driver control IC. The driving current from few milliamps up to more than 2A that depend on external powerMOSFET select. It allows high brightness powerLED operating at high efficiency for 85~265V ACpower source. Up to 300KHz precision operationfrequency that controlled by external Resistor andcapacitor. Current sense resistor decides the maximum output current to single LED or a LED string.
⊕85~265V AC power source  ⊕>90% efficiency.
⊕Controller for constant current power LED driver.
⊕Application from a few mA to > 2A LED driving current.
⊕LED string from one to hundred diodes.
⊕Precision operation frequency.  ⊕Up to 300KHz precision operation frequency
⊕SO-8 package.  ⊕AC/DC LED driver  ⊕Lighting
