Zhihong Yu, Juno Lighting Group, Des Plaines, IL; Edited by Martin Rowe and Fran Granville Power three to six LEDs from an ac- or dc-power source and charge a backup battery. LEDs find wide use in emergency lighting because of their high efficiency and control simplicity. The circuit in provides a highly efficient and reliable design for emergency LED lighting at 3 to 6 W. The circuit's input is 12 V ac, which the full-wave bridge rectifies and one or two capacitors filter into dc. The battery ... - Datasheet CS4412A-CNZ - Cirrus Logic IC, POWER STAGE, SMD, QFN-48, 4412

Jim Drew, Linear Technology Design Note 487 Introduction Redundant arrays of independent disks, or RAID, systems, by nature are designed to preserve data in the face of adverse circumstances. One example is power failure, thereby threatening data that is temporarily stored in volatile memory. To protect this data, many systems incorporate a battery-based power backup that supplies short-term power enough watt-seconds for the RAID controller to write volatile data to nonvolatile memory. ...
