Switching Voltage Regulators
The switching regulator family allows designers where power or efficiency is a concern to extend support for advanced technologies to higher power levels. Oki’s FlexipowerTM Step Down Switching Regulator allows designs up to 60 A output due to its Multiphase design. Oki also offers a Boost regulator for those designs where a higher voltage is required.
