Output 130 V / 0.5 A
IC revisionA

Description

Demonstration circuit DC2218A is a matrix LED dimmersystem featuring the LT3965 8-switch matrix LED dimmerIC. There are 16 500mA LEDs that can be individuallyturned on, off, or PWM dimmed with two 8-switch LEDdimmer LT3965 ICs. The two strings of LEDs are drivenwith two buck LED driver outputs of the LT3797 triple LEDcontroller IC. The third channel of the LT3797 serves as a30V pre-boost voltage regulator to provide a proper inputvoltage to the two buck LED driver channels. DC2218Acan be driven from a 9V to 30V input and can survivetransients up to 36V.
