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.
