FN7112.3
White LED Step-Up Regulator
Features
The EL7513 is a constant current
• 2.6V to 13.2V input voltage
• 18V maximum output voltage
• Drives up to 12 LEDs
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%.
• 1MHz switching frequency
• Up to 91% efficiency
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 maximum shut-down current
• Dimming control
1µA of supply current for V less than 5.5V.
IN
The EL7513 is available in the 8-pin TSOT and 8-pin MSOP
packages. The TSOT package is just 1mm high, compared
to 1.45mm for the standard SOT23 package.
• 8-pin TSOT and 8-pin MSOP packages
Applications
• PDAs
Ordering Information
• Cellular phones
• Digital cameras
• White LED backlighting

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.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
