Dear all,
I compare LM5001-Q1's datasheet page.17 with PMP9481 schematic.
I would like to know the difference LM5001-Q1's datasheet and PMP9481.
Relative to LM5001-Q1's datasheet, PMP9481 schematic has more parts.
I would like to know the role of these additional parts.
(PMP9481's schematic URL → http://www.ti.com/lit/df/tidran4/tidran4.pdf)
Q1. about C2 and C5
What is the purpose of these constant?
Why are these set parallel?
Q2. about R1
What is this function?
What is the purpose of this constant?
Q3.about R3 and C1
What are these function?
What are the purpose of these constant?
Q4. about R6
Is this resistor's purpose evaluation of phase margin?
Q5. about CX1/CX2/CX3
What are the purpose of these?
Q6. about L1
I think that this spec(470µH/1.6A) is pretty big.
I would like to know the design reason why this inductor is set this constant.
Q7. about C7 and C8
What are these function?
What are the purpose of these constant?
Best regards,
