Overview

CAT4026 6-Channel LED Controller with Fault Diagnostics for Large Panel LED Backlighting Description The CAT4026 is a high performance, large panel LED controller designed to control six constant current high voltage LED strings.
Added control circuitry monitors the lowest cathode voltage and generates a feedback control signal to an external Switch Mode Power Supply (SMPS) to provide a low cost and efficient solution for large panel high voltage LED backlighting.
Each LED channel current is accurately matched and controlled by sensing an external resistor in series with a low cost bipolar power transistor.
This allows current and heat dissipation concerns to be mitigated from the CAT4026 d...
