AN246/1188 1/16 APPLICATION NOTE Several performance advantages result from the use of current-mode control. First, an input voltage feed-forward characteristic is achieved ; i.e., the control circuit instantaneously corrects for input volt- age variations without using up any of the error am-...
R and C in the circuit of figure p p figure 9. The non-inverting input is not brought out 10b provide this pole. 5/16 APPLICATION NOTE The E/A output will source 0.5 mA and sink 2 mA. A It is therefore desirable to keep the value of R as low i lower limit for Rf is given ...
