Overview
26V Step-Up Converters
EUP2561
for Two to Six White LEDs
DESCRIPTION
The EUP2561 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 EUP2561 can drive 6 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 www.
