Description

The EL1848 is a constant current boost regulator specially designed for driving white LEDs. It can drive 3 LEDs in series or up to 9 LEDs in parallel/series configuration and achieves efficiency up to 91%. The brightness of the LEDs is adjusted through a voltage evel on the CNTL pin. When the level falls below 0.1V, the chip goes into shut-down mode and consumes less than 1A of supply current for VIN less than 5.5V.

The EL1848 is available in 8-pin TSOT and MSOP packages. The TSOT is just 1mm high, compared to 1.45mm for the standard SOT-23 package.
