Host detection circuit powered from primary side of the alternating current adaptor for detecting changes to a power level pulse of an information handling system

A method comprising:

• receiving, at a high impedance power delivery network, a direct current voltage from a primary side of an alternating current adaptor system;
• outputting an isolated voltage from the high impedance power delivery network to components of a secondary side of the alternating current adaptor system;
• detecting a transition in a power state identification of an information handling system associated with the alternating current adaptor system;
• generating a low voltage level pulse in response to detecting the transition in the power state identification of the information handling system;
• toggling an input voltage of a puke width modulation circuit in response to the low voltage level pulse;
• and
• alternating an output voltage level of the alternating current adaptor system in response to the transition in the power state identification of the information handling system.

A method comprising:

• detecting a first change in a power state identification of an information handling system;
• generating a pulse in response to detecting the first change in the power state identification of the information handling system;
• toggling an output of a toggling state circuit in response to the pulse;
• disabling a pulse width modulation circuit when the output of the toggling state circuit is toggled;
• turning off an output voltage provided to the information handling system when the pulse width modulation circuit is disabled;
• detecting a second change in the power state identification of the information handling system;
• generating the pulse in response to detecting the second change in the power state identification of the information handling system;
• toggling the output of the toggling state circuit in response to the pulse;
• enabling the pulse width modulation circuit when the output of the toggling state circuit toggled;
• and
• turning on the output voltage provided to the information handling system when the pulse width modulation circuit is enabled.
