ABSTRACT:
A control circuit for compensating for the change in drive current in a pe-width modulated control circuit of a power supply. Cos Mos three input NOR gates are controlled by applying an analog voltage proportional to the charge in drive current to the third input. A negative feedback loop is then provided to compensate for changing temperature.
