general description
the act6360 step-up dc/dc converter drives
white leds with an externally programmable constant
current. this device features an integrated,
40v power mosfet that is capable of driving up to
ten white leds in series, providing inherent current
matching for uniform brightness. wled brightness
adjustment is easily achieved via simple external
circuitry, which accepts either a pwm or an analog
dimming control signal.
the act6360 features a variety of protection circuits,
including integrated over voltage protection
(ovp), cycle-by-cycle current limiting, and thermal
shutdown protection circuitry.
the act6360 has a 1000ma current limit, and is
available in a small 6-pin sot23-6 package
