Part Number: LM27762EVM Other Parts Discussed in Thread: LM27762 , LMZ36002 Dear sir
I have used LM27762 for generation of +5V and -5V supply from +5V Input supply . The output voltage generated correctly but the some humming noise generated .
Please explain…
Part Number: LM27762EVM Other Parts Discussed in Thread: TINA-TI Tool/software: WEBENCH® Design Tools Dear Sirs,
We have purchased your Evaluation Module LM27762EVM. Using WEBENCH Designer, we created a Custom Design with LM27762SSR and exported it in…
Hi Athiamaan,
I am not sure if the thread you referred to was solved. It was supported by a colleague who is no longer at TI.
The LM27762 is a widely used part. We don't have any new alternative to it that has both positive and negative output rails.…
Hi Varun,
Thanks for providing the PSPICE files for the LM27762.
Regarding your query, both rails reaches to 2.2V or 2.5V. I took another scope capture to confirm and found that both rails reaching to set value i.e +/- 2.5V. See below waveform. In my…
Hi Luiz,
Apologies. Please refer to the link below.

LM27762 is still the best options because it only requires one IC to produce +/- 2.5V. Just ensure that the Vin has enough headroom to attain the desired positive and…
The LM27762EVM uses 499 kΩ for R 2 /R 4 ; the ADS1261EVM, 549 kΩ/511 kΩ. This does not answer your question, but it shows what resistors you can use safely, i.e., the input current is much less than the 2.5 µA through the divider.
Hello,
In the absolute maximum ratings GND to VOUT is specified to be at 5.8V.
I recommend you order an EVM : http://www.ti.com/tool/LM27762EVM and try the 30uF output capacitor or else and see if the regulation can suit your load specification. I think…
