FN7112.5
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.
Features
• 2.6V to 13.2V input voltage
• 18V maximum output voltage
• Drives up to 12 LEDs
• 1MHz switching frequency
• Up to 91% efficiency
• 1µA maximum shut-down current
• Dimming control
• 8 Ld TSOT and 8 Ld MSOP packages
• Pb-free available (RoHS compliant)
Applications
• PDAs
• Cellular phones
• Digital cameras
• White LED backlighting

NOTE: These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100%
matte tin plate plus anneal (e3 termination finish, which is 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.
