As switch-mode regulation technology matured, the power supply industry adapted voltage-mode control as its defacto standard. Long overlooked by all but flyback circuit designers, current-mode control simplified design of the regulation loop by effectively removing the control loop lag effects of the inductor from the output filter. As a result, the designer has to contend with a simple one-pole RC circuit instead of a two-pole LC filter. An added benefit of current-mode regulation is its ability to tolerate a wide range of input voltages, output voltages, and output currents. Not only does this increase power supply reliability in the field, it also reduces rework during the assembly process by decreasing overall sensitivity to accumulated component tolerances. With the availability of suitable control chips, current-mode control could easily displace voltage-mode control as the standard approach to switcher regulation.
