Other Parts Discussed in Thread: LM5146
Hi,
I've got a problem with one of the designs based on LM5146. All seems to function correctly except for quite high input current as for no load (it consumes roughly 50-60 mA of current depending on Vin). We've manufactured a couple of prototypes and all seem to have precisely the same effect. After reading some other threads on the forum I've checked also supplying Vcc from the Vout and it seems it helped although just a bit. Is there something that we missed in the design process ? What would be worth checking ? I've attached schematics.
