Texas Instruments Power Distributor | DC-DC and LDO

BeiLuo supplies genuine Texas Instruments power management ICs, the regulators that turn a raw supply into the quiet, stable rails that the rest of a design depends on. TI offers a broad portfolio of step-down and step-up converters, linear regulators and power-path devices, from simple 3-amp buck converters to ultra-low-noise LDOs that supply precision analog circuits. A step-down converter such as the TPS54331 integrates the high-side switch and delivers up to 3 amps from an input as high as 28 volts, with a fixed switching frequency and an Eco-mode that improves efficiency at light load, which suits industrial and consumer power supplies. An ultra-low-noise LDO such as the TPS7A4700 delivers up to 1 amp with only a few microvolts of output noise and a user-programmable output voltage, which is exactly what a precision analog or RF rail needs. Choosing a regulator is a balance among input and output voltage, current, efficiency, noise and thermal package, and the right part depends on what the rail supplies. Noise matters most for analog and RF rails, efficiency matters most for battery-powered products, and thermal performance matters for high-current rails. 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 the topology, plan the layout and verify the thermal design.
