The TLF30681QVS01 is a multi-rail supply for ADAS-applications like 77GHz short range radar, 24GHz radar, and 60GHz radar (e.g. In-cabin sensing). The TLF30681QVS01 utilizes an efficient pre-/post-regulator concept across a wide input voltage range. It features a high switching frequency battery-connected synchronous buck, an integrated synchronous SMPR-buck, and an asynchronous SMPR-boost. The device also includes under-/over-voltage monitoring, a flexible watchdog concept, and is optimized for 76-77GHz short-range radar applications within Infineon’s radar chipset.
