Angie Neo

Part Number: TPS40304

Hi,

Reference Pg 21/39, section 8.2.2.2.10 Short-Circuit Protection(R11) as seen below:

Queries:

Q1)Where can I find R11 in Figure 18.TPS40304 Design Example Schematic?

Q2)Where is Rcs located in Figure18?

Thank you,

Angie

It is R8 not R11. Looks like they copied that R11 from the design of figure 14 where Rcs is R11.

Hi John,

Thank you for the reply.

Ref Page 21/39 , the calculated value of RCS is 7.1Kohm.

May I ask why in Figure 18, RCS(RR8) is 4.02Kohm?

Why is this value chosen and how to get this value?

Looking forward to your reply,

Angie
