Infineon Technologies IR35215MTRPBF Multiphase Buck Controller

Infineon Technologies IR35215MTRPBF Multiphase Buck Controller is an 8-phase dual loop voltage regulator designed for CPU voltage regulation. This buck controller utilizes efficiency-shaping technology to deliver exceptional efficiency at minimum cost across the entire load range. The IR35215MTRPBF controller offers dynamic phase control that adds/drops phases based on load current. This buck controller also provides a digitally programmable load line, eliminating the need for any external load line setting component. The IR35215MTRPBF controller features programmable one or 2-phase operation, digitally programmable load line, Adaptive Transient Algorithm (ATA) on loops, and auto-phase detection. This buck controller provides extensive OVP, UVP, OCP, OTP, and CFP fault protection. Typical applications include Intel® VR13, VR12.5, VR12, and IMVP8-based systems, servers, high-end desktop CPU VRs, and memory VR.
