Infineon Technologies OPTIREG™ TLF35584QVHSx PMICs

Infineon Technologies OPTIREG™ TLF35584QVHSx PMICs are highly efficient Power Management Integrated Circuits (PMICs) with a multiple output system supply for safety-relevant applications. These PMICs supply 3.3V-μC to 5V-μC, transceivers, and sensors by an efficient and flexible pre-/post-regulator concept over a wide input voltage range. The TLF35584QVHSx PMCIs function with serial step up and step down pre-regulator for a wide input voltage range from 3V to 40V. These PMICs perform efficiently with a low overall power loss and provide easy realization of ASIL-D together with various Microcontrollers (μCs), enabled by multiple safety features. These PMICs are suitable for applications in electric power steering, battery management, transmission, and engine management domain control.
