SEPIC converter design
SEPIC converter design
(OP)
Hello,
i would like to design a SEPIC conveerter with input voltage ranging from 3Volts to 19 Volts . On its output will be connected three DC-DC converters ( 1 boost and 2 buck converters , their image is attached) and the output voltage of the SEPIC should be araound 8.4V.Could you help me with the design ?
Thank you.

But my circuit presents a strange response.
For pw =4.8u the response on the output is this (about 6.5V):
and the response for greater pw(e.g. 5u) is like this :
Both far away from ~8.4V.
