Abstract: A Ton/2 generator retrofits a digital tracking algorithm to an analog Constant-On-Time (COT) Controller to enable fast sensing. The Ton/2 generation is cognizant of the delay between high-side switch (HSFET) on generation and the actual turn-on time of the HSFET so that there is no deviation of sampling point, and current is reported with high accuracy. The digital tracking algorithm automatically takes higher steps during load transients to enable faster tracking and scales the measured current (Ipeak/2) based on a discontinuous conduction mode (DCM) period for DCM current reporting.

Abstract: This application relates to techniques that adjust the sleep states of a computing device based on proximity detection and predicted user activity. Proximity detection procedures can be used to determine a proximity between the computing device and a remote computing device coupled to the user. Based on these proximity detection procedures, the computing device can either correspondingly increase or decrease the amount power supplied to the various components during either a low-power sleep state or a high-power sleep state. Additionally, historical user activity data gathered on the computing device can be used to predict when the user will likely use the computing device. Based on the gathered historical user activity, deep sleep signals and light sleep signals can be issued at a time when the computing device is placed within a sleep state which can cause it to enter either a low-power sleep state or a high-power sleep state.
