ABSTRACT:
A pulse-width modulated current regulator (FIG. 4) includes a current flare out control (406,407,409,412) to limit current output at low output voltages. Current variation in an output filter inductor (408) is monitored and compared with a reference standard (407). A conduction interval is controlled in response to the comparison in order to limit current flare out.
