rgb led flood lights and white led driver

rgb led flood lights and white led driver
  General white LED current is about 20mA, but the high brightness LED 200 to 300mA current. If your product requires three to four high-brightness white LED; brightness average general practice is to string them connected together. On the market, most of the white LED driver chip can only drive 20mA. Hit a series high current LED applications will have to think of other ways. Intersil's EL7516 is a typical step-up chip. This chip operates at 1.2MHz fixed-frequency PWM mode, built-in 1.5...Continue reading
