Step-Down (Buck) Regulators, Micropower Buck Regulators, Linear Technology

Linear Technology presents a range of micropower monolithic step-down buck converters these are intended for applications that need to increase efficiency at light loads. These devices produce low standby quiescent currents when in burst mode. They can be used in applications such as high voltage power conversion, battery powered, Automotive, distributed power and Industrial power systems.

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.
