Hello, We are attempting to design in the LTC3556 into a client's consumer electronics device. However, we are unable to simulate since it is not supported. Do you happen to know if we can use the two buck converters in parallel to drive a 600mA load?Thanks,Cody
The two buck outputs of the LTC3556 are not designed to be paralleled. The bucks have separate control loops that are matched quite well but if slight differences in the internal components, pin signals do to layout, and external components can cause the bucks to not share the current well. This is a situation even if it did have a model it might simulate well but reality might be different.
Got it Marty, thanks.
