LS,
In the past I made a positive to negative converter with the LM2674M ADJ. Therefore I used AN1157.
In that time the device was manufactured by National Semiconductor.
The current boards are produced with I assume TI devices.
The positive to negative converter doesn't start-up correctly.
There is a code on the devices:
NS: CGRE
TI: 37DE
Is there something changed in the converter?
What can be done to start-up the converter correctly?
