TLF30682QVS01

Überblick

The TLF30682QVS01, member of the OPTIREG™ PMIC-family, is a multi-rail supply for ADAS-applications like 76-79GHz radar, multi-purpose camera or display cluster or center stack applications.

It’s using an efficient and flexible pre-/post-regulator concept over a wide input voltage range. The high switching frequency range of the battery connected, synchronous buck (3.3 V/3.5 A) with integrated switches allows optimization in usage of small filter components. An integrated synchronous SMPR-buck (switch-mode post-regulator) with high switching frequency enables supply for core or for memory (0.9 V-1.3 V/2.0 A). Additionally, an asynchronous SMPR-boost (5.0 V/0.25 A), running as well with high switching frequency, provides the 5 V-domain for transceiver. Integrated switches, compensation and the high switching frequency is both minimizing the number and the value of external components required.

Additional features are under-/over-voltage monitoring (via independent reference) of all integrated and up to two external rails, as well as a flexible watchdog concept to supervise the µC offers high flexibility for multiple applications.

The automotive qualified TLF30682QVS01is available in small, thermally enhanced VQFN-48 capable for automated optical inspection.

The device is optimized for 76-79GHz radar applications within Infineon’s radar chipset consisting of RXS8161PL MMIC, TC35xTA µC, and CAN-transceiver TLE9250VLE.
All features and functions are optimized to work together enabling easy, fast implementation.

Functional safety documents for TLF30682QVS01 are available on request.
