High-frequency current-mode constant on-time synchronous buck regulators

Vishay's SiP1210x synchronous buck regulators are now available from Mouser. The high frequency current-mode constant on-time (CM-COT) devices feature integrated high-side and low-side power MOSFETs. The device's power stages are capable of supplying 3A, 4A or 5A continuous current at 1.5MHz or 4MHz switching frequency. The regulators produce an adjustable output voltage down to 0.6V from 2.8V, 4.5V, 5.5V to 15V input rail to accommodate a variety of applications, including computing, consumer electronics, telecom and industrial.
