White LED Step-Up Regulator
The EL7513 is a constant current boost regulator specially
designed for driving white LEDs. It can drive 4 LEDs in
series or up to 12 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 EL7513 is available in the 8 Ld TSOT and 8 Ld MSOP
packages. The TSOT package is just 1mm high, compared
to 1.45mm for the standard SOT23 package.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
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-020.
