Hardware scheme for dynamic adjustment of DCDC converter peak current and safe LDO disable

A device, comprising:

• a controller including digital logic, wherein the digital logic includes:
• a measurement window generator configured to generate a measurement window;
• a pulse counter configured to provide a count of charging pulses on an inductor coupled to a direct current (DC)-to-DC converter during the measurement window;
• a latch configured to determine a percentage loading based on the count of charging pulses;
• and
• a comparator configured to compare the percentage loading to a load threshold, wherein the comparator is further configured to disable a low dropout (LDO) regulator based on the comparison.

A method, comprising:

• providing a load current to a load with a direct current (DC)-to-DC converter;
• counting charging pulses during a measurement window, wherein the charging pulses produce the load current;
• determining a percentage loading based on a count of the charging pulses;
• responsive to the percentage loading being below a predetermined threshold, turning off a low dropout (LDO) regulator;
• enabling a comparator after two or more measurement windows;
• comparing the percentage loading to the predetermined threshold with the comparator;
• and
• turning the LDO regulator off responsive to an output of the comparator.

A method, comprising:

• providing a load current to a load with a direct current (DC)-to-DC converter;
• counting charging pulses during a measurement window, wherein the charging pulses produce the load current;
• determining a percentage loading based on a count of the charging pulses;
• responsive to the percentage loading being below a predetermined threshold, turning off a low dropout (LDO) regulator;
• and
• adjusting a peak current setting for the DC-to-DC converter, wherein the peak current setting indicates a maximum current that the DC-to-DC converter can provide to the load.
