High-Efficiency, 40V Step-Up WLED Bias Supplies

The ACT6359 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 ACT6359 features a variety of protection cir- cuits, including integrated over voltage protection (OVP), cycle-by-cycle current limiting, and thermal shutdown protection circuitry. The ACT6359 has a 500mA current limit, and is available in a small 6-pin SOT23-6 package. By Active-Semi, Inc
