Product Details

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

Linear Technology's external power switch buck controller covers a range of input and output voltages, with current-mode and voltage-mode topologies. LTC’s Step down dc-dc controllers function in a variety of applications including Cellular phones, wireless modems, portable computers, battery powered equipment, automotive and heavy equipment and Industrial control systems.

Some devices may feature:
Multiphase operation and output tracking
Easy synchronization to external clocks

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.
