Part Number: LM2776 Other Parts Discussed in Thread: TPS60403 Hello
I have an appplication, that is sensitive to switching frequencies at about 10 bis 20 kHz. I uses the LM2667, which as a fundamentel switching frequency of 2MHz. In my application,…
Part Number: LM2776 Other Parts Discussed in Thread: TINA-TI Hi team,
We found a phenomenon in the process of applying LM2776, some doubts, would like to consult: When using LM2776 as a typical single-stage ChargePump application, through simulation…
Part Number: LM2776 Other Parts Discussed in Thread: TPS60403 Hi Team, I would like to get your comment on why our customer is getting 30kHz spurs with LM2776 design below: Please let me know if you have any questions. Thanks, Jonathan
Hi Dane,
As there is no internal latch up circuit for LM2776, I don't understand the threshold your asking for?
Could you please explain your concern and the application requirements in detail. As I said, the design for the devices your comparing…
Part Number: LM2776 Hi team,
my customer are using LM2776 in series to have -10.6V output voltage, the schematic is below.
Phenomenon: when start up at low temp( 10℃~-40℃ ), the second stage only reach -7, can't reach -10.6V. if start up at room temp…
Part Number: LM2776 Hi,
I have a problem with the LM2776 and it's not able to provide the inverted voltage. If we apply negative voltage to the test pins the LM2776 from a external power supply the part starts providing the inverted voltage.
Any…
Part Number: LM2776 Hi Team,
For the charge pump, I have some questions need to support.
1. Why charge pump can not output large current? Can we add the c apacitance capacity to achieve large current?
2. For charge pump a rchitecture, when the…
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…
