EUP2539 10 White LED Boost Converter

The EUP2539 is a constant current step-up converter specifically designed to drive white LEDs. The Step-up converter topology allows series connection of the white LEDs, so the LED currents are identical for uniform brightness. The EUP2539 switches at 1MHz, allowing the use of tiny external componen.
