Product Details

Step-Down (Buck) Regulators, Internal Power Switch, Linear Technology

Linear Technology offers a selection of step down (buck) switching regulators with both synchronous and non-synchronous internal switches. They are capable of offering 2.25V up to 30V input voltages and a variety of switching frequencies. Distributed power systems, battery powered instruments and point of load power supply are amongst several applications they may be used.

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.
