“…2, we can write the inductor current values at the start and end of a period as (4) where is the on-time duration, is the off-time duration, is the on-time inductor current slope, is the off-time inductor current slope, and is the compensation slope. Note that we consider here the general case where a compensation slope is included in the current-mode control.…”

“…T HE DESIGN of multiple-output dc-dc converters is one of the old problems studied in the 1980s and 1990s [1]- [4]. Recently, due to the advances in integrated circuit customization and the quest for versatile on-chip dc regulators, the control and circuit design of multiple-output dc-dc converters have received renewed interest [5], [6].…”

“…Previously reported control methods apply voltage-mode duty-cycle control to regulate the CCM converter while regulating the DCM converter by frequency modulation [1]- [4]. In this paper, we consider application of generic current-mode control to both converters in order to achieve faster transient responses [7].…”

Abstract-A novel method for programming current in dc/dc converters operating in discontinuous conduction mode is described in this paper. The control variable is the product of the square of the duty cyle and the switching period, i.e., 2 , which is directly proportional to input and output currents of a discontinuous-mode converter. A method of controlling 2 is applied to converters that utilize one switch (or one set of synchronous switches) for achieving two control functions. In particular a single-switch two-output boost converter, in which a continuous-mode converter and a discontinuous-mode converter share one active switch, is studied. In this system, current-mode control is used to regulate the output voltage of the continuous-mode converter and the proposed 2 control is used to regulate the other discontinuous-mode converter. The result is a generic current-mode controlled two-output converter.

“…Previously reported control methods take advantage of the insensitivity of the CCM converter to switching frequency, and apply duty-cycle control to regulate the CCM converter while regulating the DCM converter by frequency modulation [3], [4]. In this paper, we consider application of generic current-mode control to both converters in order to achieve faster transient responses [5].…”
