Abstract

A design and method for controlling the initial inductor current in a DC/DC switching regulator. The TOn or TOff time, depending upon implementation, is gradually increased such that power applied to a load is initially constrained until the system reaches a stable state, at which time normal power is connected to the load. In an embodiment, the on or off time is limited by a circuit which controls a pair of complementary transistors. The states of the transistors are controlled by the use of a startup-phase voltage and a reference voltage, which are then compared in an error amplifier. The result of the comparison is compared to a sawtooth signal in a comparator, the output of which controls the state of complementary transistors.
