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
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.
