Who LM5118 decides when to use buck and when to use boost?

It depends on duty cycle (or Vin , Vout ratio). Typically 75% is the decision point.

Thanks for replay ,
how can I decide decision point for 12VDC out put with input range 5VDC to 50VDC ?

0 EricLee over 9 years ago in reply to KDN Nandu

Hi
Assuming 12V output is in regulation, it is about 75% duty cycle when the input voltage is 16V (12V/0.75=16V)
