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…
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 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…
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…
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 have a simple…
Part Number: LM2594 Other Parts Discussed in Thread: LM2597 , LM2674 , LM2574 I'm looking for a drop-in replacement for LM259 4 MX-5.0/NOPB.
It looks like the LM259 7 MX-5.0/NOPB has some availability in the market and may be a possibility, except for…
One way to implement external UVLO can be found in the LM2597 datasheet (page 37, figure 50).
Here is a link:
May be you can use this with the LM2678 ON/OFF pin and implement UVLO for your required input range.
Cheers,
Denislav
Hey Frank, thanks for your prompt response. Unfortunately delayed start didn't worked for my app, so LM2597 looks like a candidate. I can't find info about max soft start time but I wonder is it possible to extend it to 05.-1sec? If yes than i can simply…
