hiye everyone,

recently, i have build a boost converter and when i start up the boost converter, more often than not, the power supply that supplies the boost converter overload. can anybody tell me why that happens and is there anyway i can prevent that from happening ? such as softstart ? thank you.


regards,
mengghee
 

Hi mengghee

What is your switching power supply IC?
Usualy switching PS ICs has soft start circuit.

Davood.

unfortunately, i do not have a ic controller chip. i build my boost converter off discrete component.

thank you

It may answer some of your question about switching regulator (except soft start!).
