Folks,
Id like your advise on an efficient way to boost 5VDC to 2000Vdc for a PMT (20Meg). This will be low pulse rates to the tube current will be dominated by the 20Meg voltage divider. Looking at a 10 stage VM stack and a 220Vp-p signal going in to. The stack is relatively easy but the
200Vp-p from 5V at high efficiency where I'm have lots of options.1) single inductor boost mode.
2) CT transformer with push pull transistors. (need to watch flux walk) 3) flyback. etc.designs objectives are:
relatively high efficiency (200mW out, say 400-600mW in) (5V@ ~100mA)
low profile and small footprint. (need to slide in a slot that is 1.3" x 0.5" x 8" deep It cant use much of this depth as there is would like to keep the switching part (without VM) down to
