Schematic & Wiring Diagram

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.
