EL1848
White LED Step-Up Regulator
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
level on the CNTL pin. When the level falls below 0.1V, the
chip goes into shut-down mode and consumes less than
1μA of supply current for V
IN
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.
Features
2.6V to 13.2V input voltage
14V maximum output voltage
Drives up to 9 LEDs, 3 in a series
1MHz switching frequency

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J Std-020B.
