Design Process Suggestion :
Voltage Loop Setting
?
?
?
Pole and Zero of output filter : Output inductor value, the capacitance and ESR value of the
output capacitors
Compensation Network : Error amplifier compensation & sawtooth wave amplitude.
Kelvin sense for V CORE
Current Loop Setting
?
GM amplifier current setting : Current sensing components ( DCR of Inductors ), the value of the
resistors connecting to CSN. Do Ix =
I L × DCR
R CSN
< 60uA at full load condition for better load line
?
linearity.
Over current protection trip point : This can be programmed by external resistor at IMAX pin.

I L × DCR
, I L is the inductor valley current at no load and
?
V CSN is the VIDs setting voltage.
DAC offset voltage seeting : VOSS pin external resistor programming the current source flowing
V OFFSET = 0.25 × × R FB
through the feedback resistor to set the offset voltage & compensation network resistor.
