Now i am design a power supply.
the input voltage is 3V, output voltage is 1000V/100uA.
input voltage source is two batteries.
first i use tps61040dbv boost the input voltage to 75V, nest step is boost the 75V to 1000V.
I want use capacitor pump to boost the voltage, but using some IC plan may be better.
i hope some advice.
thanks every one.
LM5017 may be a good option, it apply fly-buck Topology.
you set Vout1=50V, using 20:1 ratio transformer to set Vout2=100V.
plse refer the schematic below and find the datasheets for more details.
