Eutech Microelectronics 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.| Part No. | EUP2584 |

DESCRIPTION
The input and output capacitor can be as small as 1µF, 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.FEATURES
