SP6641B -500mA Alkaline DC/DC Boost Regulator

The SP6641 is an ultra-low quiescent current, high efficiency, DC-DC boost converter designed for single and dual cell alkaline, or Li-ion battery applications found in PDAs, MP3 players, an other handheld portable devices. The SP6641 features a 10 quiescent current, a 0.3, N- channel charging Switch 0.9V input startup, and a 0.33A or 1.0A inductor current limiting feature. The SP6641 is offered in a 5 pin SOT-23 package and provides an extremely small power supply footprint optimized for portable applications. The SP6641 is preset to 3.3V and CAN be controlled by a 1nA active LOW shutdown pin. By Exar Corporation
