EUP2584A
DESCRIPTION
The EUP2584A 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 EUP2584A switches at 1.1MHz, allowing the use of tiny external ponents. The input and output capacitor can be as small as 1µF, saving space and cost versus alternative solutions. A low 0.3V feedback voltage minimizes power loss in the current setting resistor for better efficiency. EUP2584A is enhanced with Soft-Start function and that could significantly reduce noise induced by capacitor. The EUP2584A is available in low profile SOT23-6 package.
