GENERAL DESCRIPTION

The ACT6360 step-up DC/DC converter drives

white LEDs with an externally programmable con-

stant 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 cir-

cuits, 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.
