Product Details

μModule Regulators, Dual & Multiple Output

A range of μModule (micro-module) regulators from Linear Technology providing non-isolated dual and multiple outputs. These switching regulator modules offer highly-efficiency compact solutions for DC-DC power supply applications and include switching controller, power FETs, inductors and all supporting components. The modules incorporate fault protection features including over-voltage and over-current protection.

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.
