Product Details

Step-Down (Buck) Regulators, Multiple Output, Linear Technology

The Linear Technology multiple output step down regulators have both monolithic and controller types which are either synchronous or non-synchronous configurations. These highly efficient buck regulators have input voltages up to 36 volts and switching frequencies up to 2.25MHz. Applications include telecom, networks and Industrial equipment as well as high density point of load regulation.

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.
