ZLED7000-ZI1R

Led Driver, 1 Output, Buck Step Down, 6V-40V in, 1MHz switch, 750mA out, SOT-89-5

The is a LED Driver IC for illuminated LED signs and other displays. It is an inductive step-down converter that is optimal for driving a single LED or multiple LEDs connected in series from a voltage source greater than the voltage rating of the LED. The ZLED7000 operates in continuous mode. Capable of operating efficiently with voltage supplies ranging from 6 to 40VDC, it is ideal for low-voltage lighting applications. The ZLED7000 minimizes current consumption by remaining in a low-current standby mode output is off until a voltage of >=0.3V is applied to the ADJ pin. In operating mode, the ZLED7000 can source LEDs with an output current of
