EL7513 White LED Step-Up Regulator NORTECROEMCOMMENMDEENDIDSERLD9E7PF6LO3A4RCNEEMWENDTEPSAIGRNTS DATASHEET FN7112 Rev 5.00 December 22, 2008 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 VIN 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 Ordering Information PART NUMBER PART MARKING TEMP.
