Here`s the Doug`s (passive) RCRC version. Probably needs some "tweaking" with real trafo values, in my program/simulations both R must be 2,7 Ohms and both C about 10000uF to get 12V on the 450mA load ?!
Heater - pins 4 & 5. Diodes of your choice:-), probably the best some Schottky (40V or more, 1A or more). C1&C2 voltage 25V or more.
