Automotive Cold Cranking Design Considerations
by Michele Sclocchi and Frederik Dostal, Application Engineers, National Semiconductor, Power Systems Design Europe, Jul 01 2008
Focus:
A two-switch buck boost topology maintains a well regulated, battery-powered dc supply across wide voltage range even that experienced during cold cranking of engine. This approach offers certain design advantages and disadvantages versus a conventional SEPIC converter.
What you’ll learn:
- How to build a buck-boost, dc-dc converter for automotive applications
- How to maintain regulation of automotive dc power supplies in automotive applications
- How to improve efficiency, dynamic performance, and EMI of buck-boost converters
