EUP2539 - 10 White LED Boost Converter

General Description

The EUP2539 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.

EUP2539 10 White LED Boost Converter In Thin TSOT-23 Package DESCRIPTION The EUP2539 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 EUP2539 switches at 1MHz, allowing the use of tiny external components. The output capacitor can be as small as 0.22µF, saving space and cost versus alternative solutions. A low 0.3V feedback voltage minimizes power loss in the current setting resistor for better efficiency. The EUP2539 high-voltage output stage is perfect for driving mid-size and large panel displays containing up to ten white LEDs in series.
