EUP2561, 26V Step-Up Converters

The EUP2561 is a constant current step-up converter specially designed for driving white LEDs.

The step-up converter topology allows series connection of the white LEDs so the LED currents are identical for uniform brightness.

The EUP2561 can drive 6 LEDs in series.

The brightness of the LEDs can be
