Renesas Power Distributor | Buck and Buck-Boost ICs

BeiLuo supplies genuine Renesas power management and DC-DC converter ICs, the devices that turn an input rail into the regulated rails a system needs. Renesas offers a broad power portfolio, from integrated step-down converters and dual regulators to buck-boost controllers and PMICs, built on the technology it gained with Intersil and its own design teams. A dual buck regulator such as the ISL78208 provides two 3-amp channels from an input between 4.5 and 28 volts, which suits industrial and consumer systems that need several rails from one input, while a buck-boost controller such as the ISL78263 handles an input that can be above or below the output, which suits battery-powered products and automotive systems where the rail moves across the output voltage. Choosing a power device is a balance among input range, output current, efficiency, integration and thermal package, and the right part depends on the rails and the load. Because the power stage is often the first thing to fail an EMC or thermal requirement, the layout and the thermal design matter as much as the device. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose a device, plan the layout and verify the EMC and thermal design.
