Product Summary

The LT3560IS6#PBF is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. Supply current during operation is only 16μA, dropping to <1μA in shutdown. The 2.5V to 5.5V input voltage range makes the LT3560IS6#PBF ideally suited for single Li-Ion/Li-Polymer battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. The applications of the LT3560IS6#PBF include Cellular Telephones, Wireless and DSL Modems, Digital Still Cameras, Media Players, Portable Instruments.
