Functions  
●1.5V minimum input operating  
●Supplies power for the internal circuit by step-up converter(CH1).  
●Contains step-up converter(2ch), step-down converter(4ch), ,inverting (1ch), with 31 step brightness controller for step-up converter(1ch).  
●5channels contain transistor for synchronous rectifying action mode.  
●2channels contain FETs for the step-up converter.  
●All channels contain internal compensation.  
●It is possible separately control except CH1 and CH3.  
●Operating frequency 1.2MHz(CH1~5), 600kHz(CH6~8).  
●Contains output interception circuit when over load.  
●2 channels have high side switches with soft start function.  
●Thermally enhanced UQFN044V6060 package(6mm x 6mm, 0.4mm pitch).  
○Absolute maximum ratings (Ta=25℃)
