Part Number: LM2776 Tool/software: Hello ,
I am using the LM2776 to generate a negative supply, and in the Electrical Characteristics section of the datasheet, the minimum enable voltage ( VEN(min) ) is specified as 1.2V , but the maximum VEN is not…
Part Number: LM2776 Other Parts Discussed in Thread: LMP7721 , INA128 Hello evevryone!
I have a question that may seem dumb: What is the VIN voltage range for LM2776?
When I checked the datasheet I saw that it is between 2.7 and 5.5V, in the typical…
Part Number: LM2776 Tool/software: Hello,
I would like to ask you about how to calculate the input current for the LM2776. For general converters, the input current can be calculated from the formula Input power x efficiency = output power. For a negative…
Part Number: LM2776 Other Parts Discussed in Thread: OPA2830 , Tool/software: hi Expert
We have encountered some problems in the circuit of TI's chip design for our production models, so I would like to ask you about it.
The details are as follows…
Part Number: LM2776 Tool/software: The observed failure mode is that after some amount of time in the field (within a few days), the charge pump is no longer able to output -5V and instead outputs 0 to about -1.5V while getting quite hot. The IC is being…
Part Number: LM2776 Other Parts Discussed in Thread: TL7660 I am planning to use LM2776 for VInput of 5.8V max. The operating ranges states is only 5.5V. but abs max is 6V. Please can you comment if it is okay.
Please can you also confirm that if TL7660…
