DR18EV9005-VER1.0

The EC4513 is a constant current boost regulator specially designed for driving white LEDs. It can drive 4

LEDs in series and achieves efficiency up to 90%. The brightness of the LEDs is adjusted through a voltage

level on the CNTL pin. When the level falls below 0.2V, the chip goes into shut-down mode and consumes

less than 1µA of supply current for VIN less than 5.5V. The EC4513 is available in the 8-pin MSOP packages.
