●1.5V minimum input operating ●Supplies power for the internal circuit by using charge-pump circuit which outputs a voltage twice bigger than VBATvoltage.
or a equal voltage as VBAT + VIN. ●Contains step-up converter(1ch), step-down converter(2ch), cross converter(1ch), configurable for step-up/step-down converter(1ch),
with PWM brightness controller for step-up converter(1ch). ●Contains 4FETs for the cross converter channe.l ●3channels contain
transistor for synchronous rectifying action mode. ●2channels contain FETs for the step-up converter. ●All channels contain internal compensation between inputs outputs of error amps. ●Contains sequence control circuit for ch1,2 and 4. ●Operating frequency 1.2MHz(CH1～4), 600kHz(CH5～7). ●Contains output in...
