Part Number: LM2776 Hi Team,
Does the LM2776 have an issue with startup if both EN and VIN are high? I am seeing when both are high, the device limits output to .7V and seems like UVLO. When the power is turned off and input begins to drop the output…
Part Number: LM2776 COVID-19 delayed my debugging of this enough for the thread to lock, wanted to post what ended up making this work.
The suggested TPS60400 doesn't supply enough current for my application so I was determined to get this LM2776 to work…
Part Number: LM2776 Hello team,
Could you please help me to address issue on the output voltage?
The issue is exactly same as one discussed on E2E thread here . But unfortunately this was solved offline.
I'm trying to output -5V from 5V input but my LM2776…

Part Number: LM2776 Dear support member,
My customer used LM2776.
I have a question.
(phenomenon) This part is used in the circuit of + 5V → -5V generation. About + 0.7V is output without generating -5V. (There is no switching wave form even when looking…
Hi Tao,
Thanks for helping to answering !
Hi Lars,
In your application, does LM2660 used as a doubler or inverter?
If the inverter is needed , could you try LM2776 ?
For a doubler,
How about LM2775, where Vout can be boosted ?
Part Number: OPA2830 Other Parts Discussed in Thread: LM2776 Hi team,
Could you please tell me the internal circuitry of this device? I would like to use it to study the mounting circuit.
Sincerely, Ryu.
Part Number: LM2776 Other Parts Discussed in Thread: LMZ14201 , LM2902 Tool/software: WEBENCH® Design Tools I am using LM2776 switching regulator for -5V reference in my circuit. I needed 200 mA output current from this IC for the worst case scenario.…

I'm trying to use an LM2776, but the first one I soldered in to a prototype blew up when given 5v. Since the fiducials shown in the datasheet do not exist in the actual packaging, I want to make sure that I have the orientation…
