Part Number: LM2597 Tool/software: Hi team,
Our customer wants to know the minimum ESR of the output capacitor.
I found similar question on E2E, but minimum ESR value was not provided.
Is this still unspecified?
If so, is there a common minimum value…
Part Number: LM2597 Other Parts Discussed in Thread: LMR43610 , LMR36506 We have been using the LM2594HVM-5.0/NOPB for a design for years. However, this part is not available. We also do that the LM2597HVM-5.0/NOPB is similar but the SS pin 5 is a different…
Other Parts Discussed in Thread: LM2597 Could anyone help me please to get AC Transfer Characteristic for LM2597.
While AC Analysis i get error:
Operation point not found
Component: U2.X_U1_U30.D1

Best regards, Vladimir.
Other Parts Discussed in Thread: LM2597 Hey TI.
I try to configure the LM2597 with following parameters.
Vin 30-38V, Vout 5-7V, Iout 120-200mA max.
In datasheet i to see a 330uH value for inductor, but in simulation it's 1mH. What's correct? Also, what…
How to connect the resistor divider (R1 and R2) in case of using the LM2597-ADJ as a negative voltage regulator? Page 29 of the datasheet shows a solution for the fixed voltage version
Part Number: LM2597HV Other Parts Discussed in Thread: LM2597 Hi Team,
My customer is looking for alternate source to LM2594HVN-ADJ/NOPB due to supply situation, can you please advise on the following comparing this device to LM2597HVN-ADJ/NOPB? Thanks…
Hello
The LM2597 can be used, however the DELAY pin must be left floating.
Another option is the LM2674; you need one extra capacitor for that device.
The LM2574 is another option but it is not P-to-P.
The TPS54321 seems to be in stock; but again is not…
The LM2596 has only an "on/off" or "shutdown" control for controlling the device.
Other devices in the family, such as the LM2597, have more features; such as a combined shutdown and soft-start pin called SD/SS.
The LM2596 and LM2595…
The soft-start for the LM2596 is fixed and not specified. We can not guarantee that it is longer than 200us
However, the LM2597 or LM2598 both have adjustable soft-start; one of these may be a better choice.
Hi Fabio,
I need some clarification on this statemtent "Is a neg voltage w.r.t gnd allowable on the SD ." , Which GND is the customer referring to? System GND or the GND of the part? You can have a negative voltage with respect to system GND but not to…
