CYT2506
CYT2506 is White LED Step-Up Converter manufactured by CYT.
Description
The CYT2506 is a step-up DC/DC converter specifically designed to drive white LEDs with a constant current. The device can drive two, three or four LEDs in series from a Li-Ion cell. Series connection of the LEDs provides identical LED current resulting in uniform brightness and The
Features
¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ Inherently Matched LED Current. High Efficiency: 84% Typical. Drives Up to Four LEDs from a 3.2V Supply. Drives Up to Six LEDs from a 5V Supply. Fast 1.2MHz Switching Frequency. Uses Tiny 1mm Tall Inductors. Requires Only 0.22µF Output Capacitor. Low Profile SC70 and SOT Packaging. eliminating the need for ballast resistors.
CYT2506 switches at 1.2MHz, allowing the use of any tiny external ponents.
The output capacitor can be as small as 0.22µF, saving space and cost versus alternative solutions. A low 95m V feedback voltage minimizes power loss in the current setting resistor for better efficiency.
CYT2506 is available in low profile SC70 and
