1TLF3068x application board overview
The TLF3068x Application Board is shown in Figure 1. The schematic is shown in Chapter 4 and the printed
circuit board (PCB) layout in Chapter 5. The application board includes the essential components and circuits
needed to evaluate the TLF30682QVS01 in typical user applications. A more detailed description of the
TLF30682QVS01 and its operation can be found in the device data sheet. The TLF3068x Application Board
includes:
TLF30682QVS01 Multi-Voltage System Supply IC with output filters for Buck1, Buck 2 and Boost 1
Power connectors for the battery input voltage
Connectors for all control signals including the interface to an Aurix™ microcontroller, SPI signals and
analog measurement points
Connectors for monitoring and control of two external voltage rails (VM1 and VM2)
Slammer loads for transient load tests on Buck 1 and Buck 2
Reverse battery protection for the battery input voltage –passive or active protection
A two stage (common mode and differential mode) electromagnetic interference (EMI) filter
Capability to interface to a TLF3068x Companion Board that includes an Aurix™ microcontroller
