EUP2571 - White LED Step-Up Converter

General Description

The EUP2571 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.

EUP2571 White LED Step-Up Converter In Tiny SOT-23 Package DESCRIPTION The EUP2571 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 EUP2571 switches at 1.1MHz, allowing the use of tiny external components. 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. The EUP2571 is available in low profile SOT23-5, SOT23-6 package. FEATURES z 2.6V to 5.
