Product Description

White LED Step-Up Converter

The CYT2508 is a step-up DC/DC converter specifically designed to drive white LEDs with a constant current. The device can drive two, three,four, or five LEDs in series from a Li-Ion cell.Series connection of the LEDs provides identical LED current resulting in uniform brightness and eliminating the need for ballast resistors.

TheCYT2508 switches at 1MHz, allowing the use of any tiny external components. The output capacitor can be as small as 1μF, saving space and cost versus alternative solutions. A low 95mV feedback voltage minimizes power loss in the
current setting resistor for better efficiency.CYT2508 is available in low profile
SOT-23-6package
