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.
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 components. The output
capacitor can be as small as 0.22µF, saving space and cost vers.
