方案

server, computing, telecom, and consumer electronics applications require high current point-of-load (pol) devices to power many auxiliary systems. these power supplies need to be efficient, compact, and easy to use with the ideal control, telemetry, and protection features. ldos and linear regulators are alternative solutions when extremely low noise power supplies are required, such as image sensors, ssds, and rf power. onsemi offers a broad portfolio of pol devices and linear regulators to meet a wide range of voltage and current requirements, including a growing 48-volt compatible family. from discrete parts to integrated solutions, our point-of-load products are compatible with a range of platforms.
