μModule Regulators, Single Output. Linear Technology ‘s DC/DC μModule (micro-module) regulators offer a complete system-in-package (SiP) power management solution. These step-down (buck) modules incorporate an integrated DC/DC controller, compensation components, power transistors, inductor and input and output capacitors. They offer a low EMI compliant solution with EN55022 class B standards in some products, along with output source and sink current capabilities. The compact design and high efficiency of these μModule regulators make them ideal for use in a multitude of applications such as telecom and networking equipment, Industrial equipment and ATCA cards/servers.
