Integrated Power Front End and Multi-Phase Processor Supply Automotive Reference Design(TIDA-01492)

This processor supply reference design is an automotive power solution for use in highperformance, single-core-voltage application processors in advanced driver assistance systems (ADASs). This design can support core supply currents up to 10 A at 0.9 V. The design can also operate with a wide input voltage range, withstand reverse battery conditions, and support start-stop and cold-crank down to a 3.5-V input with an undisturbed output. All switching frequencies in this solution are above 2 MHz. The design has an inherently lower electromagnetic interference (EMI) and higher efficiency due to the multi-phase configuration and integration of supplies. This reference design also provides results for conducted emissions tests for CISPR 25 Class 5.

Возможности

5A integrated 2.2MHz synchronous wide input voltage buck converter Smart diode reverse battery protection for minimum voltage drop (typical 20mV) Operating range 3.5 - 36V, supports start-stop and cold-crank Interleaved four-phase core-voltage supply minimizing ripple, EMI and inductor size Optimized for CISPR 25 Class 5 conducted emissions Small switched cap boost for 5V CAN supply reduces solution size and BOM cost
