The circuit diagram of a three channel LED driver circuit using CAT3063 is apparent here. C4 is an ascribe clarify
capacitor. R1 is the resistor acclimated for programming the achievement
current. C3 is the achievement clarify capacitor. C1 and C2 are the
accumulator capacitors of the centralized allegation pump circuit. A
argumentation top at pin 5 will accredit the IC and a argumentation low
on the aforementioned pin will drive the IC into abeyance mode. In the
abeyance mode, the quiescent accepted is about according to zero. With
the acclimated amount of R1, the LED accepted per approach will be 25mA.
When powered up the CAT6063 operates in 1X approach i.e, the achievement
voltage will be according to the ascribe voltage. If this achievement
voltage is abundant to adapt the accepted through all LEDs, the IC
charcoal 1X mode. If the achievement voltage is not acceptable abundant
to adapt the adapted accepted through the LEDs, the accessory
automatically switches to the 1.5X approach area the achievement voltage
is 1.5 times the ascribe voltage. This action is again if anytime the
IC is powered up or activate from abeyance mode.
