White LED Driver

The SE3506 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. The SE3506 switches at 1MHz, allowing the use of any tiny external components. The output capacitor CAN be as small as 1F, saving space and cost versus alternative solutions. A low 95mV feedback voltage minimizes power loss in the current setting resistor for better efficiency. By seawardinc
