Application Circuits
High Duty Cycle/Load Current Operation
The circuit in Figure 16 is used for high duty cycles (D
and high load currents. The duty cycle will begin to increase
beyond 50% as the input voltage drops below the absolute

the feedback network to introduce a low frequency lag com-
pensation (pole-zero pair) necessary to stabilize the circuit
under the combination of high duty cycle and high load
currents.
