DESCRIPTION

The SP6691 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 SP6691 is offered in a 8 Pin DFN, 5-pin SOT-23 or 5 Pin TSOT package and enables

the construction of a complete regulator occupying < 0.2 in

board space.
