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.
