LED driver circuit topologies. A better way to quantify total device eciency is to observe the total input power to the device for a given LED current drive level. The best White LED driver for a given applica- tion should be based on trade-os of size, external component count, reliability, operating range and total energy usage...Not just "% efficiency".
