Method and apparatus for improving device reliability using estimated current in a dynamic programmable switcher driver

An apparatus for adjusting a rate of closure of an electronic switch, comprising:

• an adjustable p-driver having an internal register value;
• an adjustable n-driver having an internal register value;
• a positive switch connected to the adjustable p-driver;
• and
• a negative switch connected to the adjustable n-driver.

An apparatus for adjusting a rate of closure of an electronic switch, comprising:

• a logic comparator;
• an exclusive OR gate;
• an AND gate connected to the exclusive OR gate;
• an inverter for enabling a pulse width modulation connector to the AND gate;
• an inverter for dynamically selecting a positive driver, input to the AND gate;
• and
• a switch connected to the AND gate.

An apparatus for adjusting a rate of closure of an electronic switch, comprising:

• means for estimating the load current of the Buck regulator;
• means for comparing the current flow estimate with a predetermined threshold;
• means for slowing a rate of closure of a switch when the current flow estimate is greater than the predetermined threshold;
• and
• means for increasing the rate of closure of a switch when the current flow estimate is less than the predetermined threshold.

A non-transitory computer-readable medium containing instructions for adjusting a rate of closure of an electronic switch, which when executed cause a processor to perform the steps of:

• estimating a current flow through a logic comparator;
• comparing the current flow estimate with a predetermined threshold;
• slowing a rate of closure of a switch when the current flow estimate is greater than the predetermined threshold;
• and
• increasing the rate of closure of a switch when the current flow estimate is less than the predetermined threshold.
