Boost Converter for 2 LED Strings
Description
PMP10521 is a boost converter for LEDs which utilizes the LM5020-2 controller. The switching frequency is set to 100 kHz for high efficiency at a nominal output power of 18.5W. The design features switch current limiting: output over-voltage limiting and summing feedback for multiple LED strings. Constant current regulation allows for wide variation of output voltage.
