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 computers. Numerous
benefits include greater simplicity, lower cost, higher
efficiency, longer bulb life, and greater reliability when
compared to fluorescent (CCFL) and electrolumines-
cent (EL) lamps.
The MAX1698/MAX1698A are switch-mode boost con-
trollers 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 typical-

The MAX1698A has a higher, and more accurately
specified, CS current limit than the MAX1698 for higher-
power applications of 5W or more. Both devices are
supplied in a space-saving 10-pin μMAX package that
occupies half the space of an 8-pin SO. An evaluation
kit (MAX1698EVKIT) is available to speed designs.
