Abstract
A voltage margin setting interface circuit has a single input pin, and is configured to program the slew rate and polarity direction of variation of the operation of a digital-to-analog converter, such as may be used to set a reference voltage level, for application to an error amplifier of a voltage regulator circuit of the power supply of a personal computer. A DAC clocking control circuit is coupled to an output port, and to respective DAC increment and decrement ports, and is operative to control the magnitude of output current, and to assert an output signal at one of the increment and decrement ports, in accordance with a prescribed relationship between the voltage and upper and lower ranges of the input voltage relative to its middle value.
