Part Details for TLVH431 by Texas Instruments

The PMP11302 is a high voltage (166VAC to 528VAC) Buck converter design using UCC28881 with an series connected external MOSFET to achieve high voltage conversion ratio. 24V/100mA is provided by the UCC28881 Buck converter and followed by a TLV70450 LDO to provide 5V/20mA output.

TIDA-00746 is a 17W system-optimized SMPS design for automotive infotainment processor power. The design has been tested for and passed CISPR25 Class 5 conducted EMI  limits.  All buck converters used in this design is switching above AM band (>1.85MHz).The design is divided into four major blocks:Front end protection:  Various protections have been implemented: such as those against positive and negative pulses (ISO7630 Pulse 1: 2a: 3a/b) through TVS: reverse terminal protection through innovative smart diode (LM74610): and battery disconnect switch with OVP protection (PFET).EMI filter: a common mode and a differential filter for conducted EMI suppression.Low EMI front end DC/DC converter: LM53635-Q1 is a switching: synchronous 3.5A buck regulator and is used as a front end DC/DC converter in this design. This 2.1 MHz part is automotive optimized and has low EMI. Apart from the spread spectrum option: the device comes in an automotive-qualified Hotrod(TM) QFN package with wettable flanks: which reduces parasitic inductance and resistance while increasing efficiency: minimizing switch node ringing: and dramatically lowering EMI.Downstream POL buck converters such as: LM26420-Q1 (Integrated dual buck): TPS57114-Q1: and TPS57112-Q1: all POL switchers used in the design switch above AM band. For high frequency noise-sensitive rails: a ferrite bead filter is used.

This camera hub reference design allows connection of up to four 1.3-megapixel cameras to a TDA3x system-on-chip (SoC) evaluation module (EVM). Each camera connects to the hub through a single coax cable. Using FPD-Link III connections: the cameras are connected to a four-port deserializer. The output of the deserializer is MIPI CSI-2. The design also allows connection of other types of sensors for sensor fusion use cases.

The ADAS Sensor Interconnect Board is intended for applications where remote sensors like cameras: LIDAR or radar modules need to be connected to a central processing ECU. The board supports up to 3 coaxial and 1 LVDS twisted pair data inputs as well as 3 FMC cable and 1 board to board connector as data outputs to a processing ECU.  Camera or other sensor modules connected through the coax connector (SMB standard) are powered directly via the coaxial cable (power over coax) from the interconnect board. Because of an independent complete power solution for all ICs and power over coax on board: a single car battery or similar wide voltage supply can be directly connected to the power connector on the ADAS Sensor Interconnect Board. An on-board uC and LIN interface allow control and configuration of the Interconnect board as well as plug-and-play operation.

This reference design includes a complete power management solution for a standalone emergency call (eCall) system in an automotive environment. The circuit is supplied directly from the car battery rail. It also manages a backup battery to power the eCall system while the car battery rail is not available. It includes power path management which routes the available power rail directly to four DC/DC converters which are supplying the required functional blocks of the eCall system. The solution is optimized to operate at maximum efficiency while powered from the backup battery.
