MAX1698A Datasheet | Maxim Integrated

.. 19-1621; Rev 2; 2/07 High-Efficiency Step-Up Current Regulator for LEDs General Description The MAX1698 and MAX1698A are efficient drivers for white or color LEDs. They are ideal for large LED backlit displays in PDAs and laptop puters. Numerous benefits include greater simplicity, lower cost, higher efficiency, longer bulb life, and greater reliability when pared to fluorescent (CCFL) and electroluminescent (EL) lamps. The MAX1698/MAX1698A are switch-mode boost controllers in which LED current, rather than output voltage, is regulated The devices drive series-connected LEDs with a controlled current that is measured with a typically 15Ω sense resistor, not an...
