SP6690 Micro Power Boost Regulator Series White LED Driver FEATURES
NC 1 8 NC ■ High Output Voltage: Up to 30V FB 2
SP6690
7 SHDN ■ Optimized for Single Supply, NC
8 Pin DFN
3 6 V 2.7V - 4.2V Applications IN ■ SW Operated Down to 1V 4 5 GND ■ High Efficiency: Greater Than 75% Now Available in Lead Free Packaging ■ Low Quiescent Current: 20µA
APPLICATIONS
■ Ultra Low Shutdown Current: 10nA ■ White LED Driver ■ Single Battery Cell Operation ■ High Voltage Bias ■ Programmable Output Voltage ■ Digital Cameras ■ 1Ω switch (250mV at 250mA) ■ Cell Phone ■ Miniature Package: 8 Pin DFN, ■ Battery Backup 5 Pin TSOT or 5 Pin SOT-23 ■ Handheld Computers
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.
