OK, that one I already had (Vo = Vin/1 - D). So working backwards from my empirical results (3V in, ~9V out), we can see that I have a duty cycle of 2/3. Not bad (>50%) for such a crude circuit, eh?
Here are the other formulae I have:
Inductor size: L = (Vin Ton)/Ipk
Peak current: Ipk = 2 Iload (Vo/Vin)
Switching frequency: Td = (L Ipk)/(Vo - Vin)
Td = (Vin Ton)/ (Vo - Vin)
(where Ton = T - Td)
So do you have any comments about any of the circuit aspects I asked about? Voltage regulation? eliminating intermediate transistor?
