2 System Overview

The battery power connects to the 12-V input terminal, J10. The wide VIN buck, LM62460-Q1, is used to convert this 12-V input to a 3.3-V output. The LP876242-Q1 then takes the 3.3-V input and creates, 1.8-V, 1.2-V and 1.0-V rails. To maintan a low-noise supply, the 1-V rail is filtered to create a clean input rail for the radio frequency (RF) section of the radar.
