Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: LM2611EVAL Tool/software: Bought the LM2611EVAL last week. Powered up yesterday for the datasheet configuration. 5V in, -5V out. First with no load. It could not produce -5V. Can the eval board circuit handle no load? Also tried with a load…
Part Number: LM2611EVAL Other Parts Discussed in Thread: LM2611 , , LM2776 , LM2775 Dear,
I bought the EV of the LM2611 device. I tested the performances: Vin = 5V
- Without loads (Iout = 0 mA), the convertor is operationnal
- If the output current…
Part Number: LM2611EVAL Other Parts Discussed in Thread: LM2611 Hi,
For our validation, we wired the LM2611EVAL board according to the schematics below. After connecting the load to the EVM, we are experiencing the problems described below.
For maintaining…
Part Number: LM2611EVAL Other Parts Discussed in Thread: LM2611 , I am trying to use the LM2611EVAL to demonstrate a 3.3V to -12V regulation setup. The load current requirement is 150mA. From the figures and calculations in the datasheet, this should be…
Hi Arun,
Thanks for using the e2e forum. I had a look at your schematic. It looks to me like the FL2 inductor is not connected properly. In the current schematic, there cannot flow a DC current through the inductor. The diode would need to be placed on the…
Hi Sneh,
Thanks for using the e2e forum.
Unfortunately, we do not have a simulation model for the LM2611 device. The only resource we have for this part is an EVM board: https://www.ti.com/tool/LM2611EVAL
I am very sorry for this inconvenience.
Best regards…
Hi EM,
Thanks for your reply, I made up the above schematics by wiring on the LM2611EVAL EVM board. When I power on the device, the input (12.5V) becomes 1.6V, and the output of the regulator was -7.5V. Could you please let me know why input becomes 1.6V…
