| Looking for advice/critique on Power Supply module schematic |

Hello all, I've been spending a few days on a schematic for a DC-DC converter module that uses the LM22578 Simple Switcher buck converter as a tracking pre-regulator and it is set to output about 2V above V-Out. The 2 LT3081's are used as the linear output stages and they perform the voltage and current adjustment. The LT3092 is used to set the maximum output voltage however it may not be used in the end since I'm using some DAC's on a separate board to control the module. Finally the LM2682 is used to create a -10mA current source to allow the output of the LT3081's to reach 0V. This design is based on the popular DC2132 power supply but I've added a bunch of extra goodies that aren't really important here. For reference, I will be inputting 34v DC and the output will be adjustable from 0-32v @ 0-3A. In any case, I was wondering if you guys would mind taking a look at my schematic and give me some critique/advice on it, anything constructive is greatly appreciated! If you guys see any faults with my schematic or problems that would keep it from working please let me know. I look forward to getting some feed back! Thanks! |
