No reasonable answer possible without knowing the input voltage range.if i want to supply 10v @ 1A for a 10ohm load, why wont i use a boost ? or buck-boost?
Dear checkmatemore power FETs.

Hi
Why more power fets ? each buck boost , just has one power mosfet . ( an inductor and a diode and a capacitor and a switch ) isn't it ?
Best regards

If we don't restrict the topology, an universal would be described to have four switches, at least two of it active (transistor) switches. 1 to 42 V input voltage is possible but involving some overhead according to the high maximum input current for 10 W output.each buck boost , just has one power mosfet . ( an inductor and a diode and a capacitor and a switch )
Ok , then you see below , please :

It is derived from professor Marty brown's book .

In cases, where a basic buck (Vin > Vout) or boost (Vin < Vout) converter can be used, it will be used, because it means less area, cost and losses.And yet buck is being used vastly. See on pc motherboards....why won't they use buckboost or boost? They all can provide the cause...arnt they?
