Description
This application note describes a simple Dual-Channel SMPS LED driver with an on-chip dimming engine that alleviates typlical problems. In fact, the integration of the dimming engine into the SMPS control is such that higher dimming PWM rates are possible, making the design highly effective in high-end applications like LED backlights, automotive systems, medical systems, and especially image processing systems.
