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 or start up at room temp and then decrease temp to -40℃, it won't have this problem.
Q:
1. what would possible cause this?
2. I read some of the thread, it seems LM2776 has known problem during start up, is this correct?
