A range of SEPIC DC-DC Converters from Linear Technology which can be used in applications where the output voltage may be either higher or lower than the input voltage. The SEPIC (Single-Ended Primary-Inductor Converter) topology also allows these converters to produce a negative output from a positive input voltage. Some of these switching regulators include features such as multiple outputs, programmable current limit, low battery detection and burst-mode operation.

Switching Voltage Regulators, Linear Technology

Linear Technology product series of synchronous and non-synchronous internal switching regulator ICs offer high efficiency plus a wide input voltage range and switching frequencies up to 4MHz.
The controllers span over several types of configurations from buck (step-down), boost (step-up), buck-boost, forward, Isolated, Inverting and flyback controllers. The Flyback, Forward and Isolated Controllers primary and secondary side provide a solution to help replace the DC/DC bricks that get used in back-plane power conversion.
