Because of flux inbalance i dont want to use voltage mode controller. What i should care if i use voltage mode?
I found some current mode ics but all of them work at higher frequencies. Do you know any current mode ic for this application?
Hi to all,
I'am designing 1kW push-pull converter. Design specs are below;
60VDC input
20kHz to 100khz operating frequency. ( Fixed but i could change it)
400VDC-2.5A output
I'am looking for analog controllers for this converter. So far i found TL494/TL594 controllers but these voltage mode...
I can first divide dc voltage by two with two series cap(also 2 series resistor for be sure voltage is divided equally) then use 600-800V integrated mosfet buck controller to make 12V(such as st viper06). Then put ldo to make 5V from 12V.
Actual maxiumum voltage is around 800VDC. I found ST viper16 buck converter but it has 800V mosfet. Also found FSL4110LR flyback controller with 1000V mosfet but with reflected voltage and spikes in flyback voltage can go above 1000V i guess. It's look i have to use external mosfet. For buck...
Hi to all,
I need a cheeap solution for 900-1000V to 12V buck converter. Output power is 1W. Is there any monolithic power ic for this? If not what do you suggest ?
