This section presents a high level overview of automotive board net and the describes the conditions that the the tests simulate. These include:
- Reverse polarity
- Jump start
- Load sump
- Starting profile
- Superimposed ac
This section presents an approach to architecting the dc-dc conversion stage to handle the transients on automotive battery rail. Following topologies are covered:
- Always-on boost + buck
- On-demand boost + buck
- Buck + post boost
Pro/cons of the different approaches are also discussed.
This section presents the different methods of protecting the electronic loads connected to the automotive battery rail in the event of accidental reverse battery connection. The methods covered include:
- Schottky diode
- PFET + discretes
- Smart diode + NFET
This section presents the buck-boost dc-dc converter as an effective and efficient solution for the wide vin automotive battery rail. The advantages compared to pre-boost and two stage solutions are presented. Also contains an overview of buck-boost converter and controller offerings convering various current and power levels.
