SC656ULTRT Product Details

SC656ULTRT Overview


20-UFQFN Exposed Pad saves board space. The LED driver's design uses 7 outputs.The led light driver is mounted using Surface Mount.In this case, the result is a DC DC Regulator with high efficiency.It is able to work normally at the operating temperature of -40°C~85°C TA.Backlight has significant advantages.As a result, it operates based on the frequency of 250kHz.In this case, the termination value is 20.The LED light driver is configured with a base of 0 pins.Undetermined failures will occur if the voltage supply is less than 2.9V.It is estimated that there are 7 segments.It's mounted by Surface Mount.There is no problem with the voltage of 5.5V.In this device, the output voltage is 2.5V~5.25V volts.On this device, there are 20 pins.

SC656ULTRT Features
