Infineon TLF30681QVS01XUMA1

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/2.3 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/1.0 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 TLF30681QVS01 is available in small, thermally enhanced VQFN-48 capable for automated optical inspection.The device is optimized for 76-77GHz short range radar applications within Infineon’s radar chipset consisting of RXS815xPLA RASIC™ MMIC, TC33xDA AURIX™ µC, and CAN-transceiver TLE9250VLE. All features and functions are optimized to work together enabling easy, fast implementation.Functional safety documents for TLF30681QVS01 are available on request.To get access to the complete OPTIREG™ PMIC technical documentation please follow the instruction here.

Symbol Views

(not all views will be available for every part)

Normal: Standard and most popular representation of schematic symbol

ALT_1 (IEEE view): Symbol representation in a way that is more graphical in explaining what the purpose of each pin is. For connectors and most discretes (as we use these views) it is simply an alternate view for people to use depending on the situation. For instance connectors can be generally an input, an output or neither. Resistors can be vertical or horizontal.

ALT_2 (demorgan): Demorgan is a name for an equivalent Gate structure. so for instance an AND gate and an OR gate can be represented by its Demorgan equivalent of a NOR gate.

Sometimes a device is fractured into multiple symbols (often for high pin count parts). If that is the case, you can preview the different symbols that make up the device by selecting them in this drop down.

Footprint Views

(not all views will be available for every part)

Basic: Our standard footprint view showing, contact area, pin number, top, top assembly

Detailed: Additional info to help you evaluate the part and the footprint including: dimension, silkscreen, soldermask, and solderpaste

PinDetail: Highlights the pin to pad contact area dimensions

Displays min/typ/max pad sizes for footprint per IPC specification (not all sizes will be available for every part)
