1W flyback with bias winding

Hello,
We need to do a flyback to switch off the 380VDC PFC bus. We need a isolated secondary output of 5V,0.2A, and we need a 12V, 0.1A bias rail to feed the main PWM controller with. We'd rather have a lower switching frequency than 100KHz due to switching losses with our 380VDC input. Could you recomend something, eg LNK or TNY etc etc?
Hi,
