APPARATUS AND METHOD FOR MEASURING LOAD CURRENT WITH HIGH RESOLUTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18394006 titled 'APPARATUS AND METHOD FOR MEASURING LOAD CURRENT WITH HIGH RESOLUTION

Simplified Explanation

The abstract describes a method of measuring load current in a switching converter by generating a pulse based on a reference voltage and on-time of a power switch, filtering the pulse to generate an output signal, and switching modes based on the load current value.

• Obtaining a first reference voltage defining the peak of an inductor current passing through the inductor.
• Generating a pulse based on the first reference voltage and the on-time of the power switch.
• Filtering the pulse to generate an output signal.
• Switching from a first mode to a second mode when the load current value is less than a first threshold value based on the output signal.
• Extending the width of the pulse in proportion to the on-time in the second mode.

Original Abstract Submitted

A method of measuring a load current provided to a load of a switching converter includes obtaining a first reference voltage defining a peak of an inductor current passing through an inductor of the switching converter, generating a pulse based on the first reference voltage and an on-time of at least one power switch of the switching converter, generating an output signal by filtering the pulse, and setting a second mode from a first mode when a value of the load current is less than a first threshold value based on the output signal. The generating of the pulse further includes generating the pulse having a width extended in proportion to the on-time in the second mode.
