概觀

The IS31LT3363 provides a simple circuit for multi channel LED dimming solution. It saves two extra power stages for typical RGB application thereby reducing external circuitry while maintain a high efficiency. It has a built-in buck current regulator that provides excellent current tracking and dimming performance. The dimming range will be greater than 10,000:1 at 100Hz dimming frequency. PWM frequency can be set between 100Hz~20kHz. This dimming solution can be designed to be noise free making it an ideal choice for household and commercial lighting products. For this application, user often needs a MCU and an interface part, IS31LT3363 integrates a LDO to provide 3.3V bias power for the external IC’s. An automatic current foldback function allows power savings when all the three LED strings turn off time is longer than 10ms. Open LED and over temperature protection ensures robust operation. IS31LT3363 can operate over an input voltage to 36V. It comes in a thermally enhanced eTSSOP-16 package.
