The CAT is an 8 channel constant current driver for LED billboard and other general display applications. LED channel currents are programmed together via an external RSET resistor. Low output voltage operation on the LED channels as low as . Constant Current LED Drivers. When your LED light engine needs constant current drive and control as part of the assembly, our constant current LED drivers are the appropriate LED driver solutions. We maintain a broad selection of stocked LED drivers. Our modernized LED driver offerings include the latest products to help meet THD, DLC and Energy Star . HV is an open-loop, Average-mode current control LED driver IC operating in a constant Offtime mode. The IC features ±2% current accuracy and tight line and load regulation of the LED current without any need for loop compensation or high-side current sensing. Its auto-zero circuit cancels the effect of both.

Cost-efficient, reliable and easy to use. Our linear constant current LED drivers are a simple and robust solution to drive low- and medium-power LEDs up to mA – making up the vast majority of applications in the growing LED market. The AEC-Q qualified NCR devices are easy-to-use, reliable, cost efficient, and do not affect EMC. Constant current LED drivers are designed for a designated range of output voltages and a fixed output current (mA). LEDs that are rated to operate on a constant current driver require a designated supply of current usually specified in milliamps (mA) or amps (A). The STCS2A is a BiCMOS constant current source designed to provide a precise constant current starting from a varying input voltage source. The main target is to replace discrete components solution for driving LEDs in low voltage applications such as 5 V, 12 V or 24 V giving benefits in terms of precision, integration and reliability. Current setting The current is set with an external sensing resistor connected to the FB pin.
