 		 #172991 - reverse engineering
Responding to: Richard Erlacher's previous message
I had a customer with obsolete special cameras who's hybrid dc converter module is damaged and we couldn't locate the parts. What I managed to dig out from the manual was the battery voltage between 9.5 to 14 volts and the battery is quite small, half hand full. and current rating is 350mA as I stated earlier.
We did the design using power op amps but I was thinking of simpler ideas because we are really pushed for space for this design. And in the manual it said one part of the regulator feeds ultra low noise video preamplifier.
The good news if my design is successful I will sell 30 pieces at a good price.
The original dc module was made on a ceramic pcb and it has 18 pin SIP.
Regards
Mahmood
