Other Parts Discussed in Thread: LM5150RUMEVM, LM5155
Hi guys,
I'm looking for a solution of Automotive cold crank power management.
For LM5150RUMEVM www.ti.com/tool/LM5150RUMEVM, which the input voltage range is from 2.5V to 40V.(Requires minimum 6V voltage to start-up)
1) What's the reason for the requirement of the 6V start-up voltage?
2) How to modify the solution to be suitable for cold crank? (In another word, the board can be started up from 3.2V rather than 6V.)
Thank you very much.
