EUP2584

The EUP2584 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 EUP2584 switches at 1.1MHz, allowing the use of tiny external components. The input and output capacitor can be as small as 1F, saving space and cost versus alternative solutions. A low 0.25V feedback voltage minimizes power loss in the current setting resistor for better efficiency. EUP2584 is enhanced with Soft-Start function and that could significantly reduce noise induced by capacitor.

The EUP2584 is available in low profile SOT23-6 package.
