3. ### High Voltage Regulator (50V), ultra low power consumption?

regulartor 50v Of course, I have two input: 1) High voltage input (60V) 2) "control" voltage (0 - 3.3V or 0-5V) I want to control High voltage input with "control" voltage. The same idea as in the Horowitz's book ...
4. ### Need microcontroller that supports USB and have flash memory

Re: uController usb based ? I worked with F320. You can buy development kit (240$), and you will not have problems at all. With kit, you will get IDE and limited compiler (I think 2 KB, maybe 4 KB). If you need to do something bigger than that you can buy KEIL compiler (2200$). With this kit...
5. ### High Voltage Regulator (50V), ultra low power consumption?

low power consumption voltage regulator I need idea for the ultra low power consumption High Voltage regulator. Input 60V (or even 150V). I want to have linear regulation on the output between 2V and 50V. I have Input between 0V and 3.3V (maybe 5V) and I need proportional output between 2V...
