Automotive Wide Vin Front-End Power Reference Design w/Cold Crank Operation & Transient Protection
Description
The TIDA-01179 reference design is an automotive front-end power supply that is able to supply 30W maximum output for the 12V car battery. The first stage is a buck-boost DC/DC converter that maintains a stable 15V output voltage over the full DC range of the 12V battery conditions specified in ISO 7637-2 and ISO 16750-2 standards. The second stage is a compact buck converter that enables up to 20W output.
