Hi,
Pg 226 (attached) of Basso's book "SMPS" has an expression (2A-1) for the Transfer function of the voltage mode buck (CCM)
power stage.
The expression for Q is written and has a bit as follows.... "rcf + rlf//R"
where:
rcf = output capacitor ESR
rcl = output inductor ESR
R = Load resistor
..but shouldnt this be "(rcf + rlf)//R"?
