White LED Step-Up Converter

In Tiny SOT-23 Package

FEATURES

DESCRIPTION

2.6V to 5.5V Input Range

The AAP2584 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 AAP2584 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.

AAP2584 is enhanced with Soft-Start function and that

could significantly reduce noise induced by capacitor.
