DESCRIPTION
The SP6690 is a micro power boost regulator that is specifically designed for powering series
configuration white LED. The part utilizes fixed off time architecture and consumes only 10nA
quiescent current in shutdown. Low voltage operation, down to 1V, fully utilizes maximal battery
life. The SP6690 is offered in a 8 pin DFN, 5 pin TSOT or 5 pin SOT-23 package and enables the
construction of a complete regulator occupying < 0.2 in2 board space.
