Hi Folks
I am gonna have a onsite interview about LDO and DC-DC converter. I need some suggestions or even some interview questions about these . I know the guy will interview me is trick tester and he likes to give some tricky questions about power conversion and I just start to learn power electronics this semester and don't have an deep understanding so I am so worried about this.
I am eagerly looking forward to the suggestions or interview question from you guys!!!
Dear cqdevil :
I think you really need to do some homework :
1.Some performance definitions.
(eg: line regulation / load regulation)
2.LDO loop transfer function.
3.How to compensate LDO ?
1-what is the other name for dc-dc converter.
2-what is its quardant of operation.
3-what elements are used in dc-dc converter.
4-draw its schematic diagram.
5-what is the class of dc-dc converter in rectifiers.
Some questions for LDO
(1) What is dropout voltage, how to decrease it?
(2) Basic topology for LDO
(3) Compensation scheme for LDO
(4) Bandgap design
(5) What is the difference between NMOS/PMOS output FET
