Description

This reference design details a power management circuit which is capable of supplying all rails of a CMOS camera supply.  All rails, even highly sensitive analog rails of the image sensor, can be supplied directly without the need of additional filters. This way the power management solution can acheive highest efficency. The implementation is based on 3 completely integrated step down converter circuits enabling a small total solution while still capable of handling up to 200 mA at each of the outputs.

Features
  • 3 low noise output voltage rails
  • Highest efficiency for all 3 output voltage rails
  • Small solution
  • Up to 200 mA output current per rail possible
  • Simple design, small BOM
  • Automotive qualified components
