SRI-1.8-1.0 | Inductorless switching regulator
Low power and low leakage applications require flexible and efficient power conversion to adapt the islet voltage supply to the function mode and reduce the power consumption. It scales down the regulated 1.8V core voltage to 1V reducing the power consumption of the logic block by a factor of 4 to 6.
The combination of a high efficiency and a low quiescent current makes SR-1.8/1.0 the ideal integrated companion of logic blocks targeting low power SoCs.
Its innovative inductor-less architecture stands out on BOM reduction making it the ideal solution for highly integrated applications.
Key benefits
