Product Details

Switching Regulators, Ultralow Noise Regulators, Linear Technology

Linear Technology switching regulators incorporate synchronous and non-synchronous internal switches. This range offers ultralow noise switching voltage regulators and is suitable in sensitive RF or audio circuit environments. They have a selection of input voltages and switching frequencies with good efficiency. Typical applications include Industrial supplies, wall transformer regulation, automotive battery regulation and distributed supply 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.
