AC/DC LED Controller, DC/DC LED Controller and LED Drivers for RGB Clusters

AC-DC LED Controller

Step-Down AC-DC controller IC with integrated driver for separate power stage. The on board driver is able to switch Mosfets with up to 3A output current. Very high efficiency over the input voltage range with output accuracy of +/-5%. LED current dimming possible via DIM pin.

DC-DC LED Controller

Step-Down constant current DC-DC LED driver with integrated power switch. Only 4 external components for full protected constant current source required. Very high efficiency of 96% over entire input voltage range due to PFM control. Dimming function integrated on board with external clock signal.

LED Drivers for RGB Clusters

Constant current driver with adjustable current for each channel by three external resistors. Two selectable gray scale Modes (16/10bit) with embedded or external clock signal. High quality monitoring without flickers due to S-PWM technology. Excellent output accuracy between each channel and IC (typ. +/-3%). Clock reverse function supports long distance data transmission. Reliable and simple data transmission due to Daisy-Chain topology and two wire interfaces.
