I tried to solve it with adding enough capacity to the output voltage, wasn't happy with the needed physical space. I I was controlling the PWM with an microcontroller, the voltage controlling is quite slow (ADC needs time). So I am now going to try it with an MC34063 IC, that should work.

Did you ever calculate the efficiency of your DC-DC converter? How big is it?
