EUP2595 - 32V Step-Up Converters

General Description

The EUP2595 is a constant current step-up converter specially designed for driving white LEDs.

The step-up converter topology allows series connection of the white LEDs so the LED currents are identical for uniform brightness.

The EUP2595 can drive 9 LEDs in series.

EUP2595 32V Step-Up Converters for Two to Nine White LEDs DESCRIPTION The EUP2595 is a constant current step-up converter specially designed for driving white LEDs. The step-up converter topology allows series connection of the white LEDs so the LED currents are identical for uniform brightness. The EUP2595 can drive 9 LEDs in series. The brightness of the LEDs can be adjusted through a voltage level on the CTRL pin or by applying a PWM signal to CRTL pin. 1MHz current-mode, pulse-width modulated (PWM) operation allows for small input and output capacitors and a small inductor while minimizing ripple on the input supply/battery. Programmable soft-start eliminates inrush current during startup. The EUP2595 is available in a space-saving, 8-pin 3mm x 3mm TDFN package.
