Texas Instruments LM5127QRGZRQ1 | Demoboard PMP23194

Description

This reference design provides power for automotive Advanced Driver-Assistance Systems (ADAS) to power cameras (8 V), Controller Area Network (CAN) communications (5 V) and main processor (3.3 V). Operation is over the full automotive range including battery voltage surges to 34 V and dips to 6 V due to cold cranking. The design is low noise to meet the stringent CISPR 25 Class 5 emissions requirements and include an input filter. The board is designed for ease of test providing jumpers to disable each output and an on-board dynamic load for the high current of 3.3-V output. The test report includes operational data on each output and conducted emissions scans for the complete design against CISPR 25 Class 5.
