PMIC powers high current cores through DrMOS technology

A universal PMIC, which drives up to four independently controlled external DrMOS power stages at currents greater than 40A, has been released by Exar. Suitable for the latest 64-bit ARM processors, FPGAs, DSPs and ASICS, the XR77128 features the company’s programmable power technology, which allows for a low component count, rapid development, easy system integration, dynamic control and telemetry. To meet a wide range of output current requirements, each output can be independently configured to directly drive external MOSFETs or DrMOS power stages.
