Hello, everyone,
I am in need of a low current (less than 10mA) DC-DC voltage doubling circuit with SMD parts to fit in a very small PCB footprint. I started out doing research to make my own but most everything I have found involves AC-DC. The small number of examples that I found which are actually DC-DC involve a MOSFET device that switches between capacitors in series, but no guidance on what voltage to feed the gate to create the switching effect. I do not have the time to figure this out and I also despise dealing with power in audio circuits which has become the biggest headache when trying to complete projects. Requirements for the circuit are as follows:
- Input voltage: 45-50VDC
- Input current: less than 10mA
- Output voltage: 90-100VDC
- Output current: 4-10mA
- Fewest parts possible for stable output voltage
- Circuit has to be tested and known to work as required
The last part is especially important. I do not have time to test and verify. A schematic with complete BOM including alternative part numbers is to be delivered upon payment.
Thanks!
Paul
