Part Number: LM2776 I am using the LM2776 to supply the negative rail of a dual supply rail to rail in & out op amp. If the LM2776 has no output for the negative rail but the positive rail is still there, will the op amp swing to the positive rail or…
Part Number: LM2776 Hello
i have designed a negative 5V supply with the LM2776DBVR
as i read the datasheet i'm not sure what would be the best C FLY to chose ?
i chose 2 x 4.7uF ?
for the input / output i chose 10uF / 10uF (although the EVM has…
Part Number: LM2776 I am getting Vout = -0.7V for the LM2776 part with the following conditions:
Vin = 5.5V
C between pins 5 and 6 = 1 uF
Cout = 2.2 uF
Any clues what might be happening here?
Thanks,
John
Part Number: LM2776 Hello team,
The output ripple measurement graph (Fig 1) is very different from the output ripple calculation equation (equation 4) on the datasheet.
The shape of the graph on Figure 1 is not linear. What is the condition of the…
