POWER CONVERSION SYSTEM AND METHOD

摘要

A power conversion system (10) includes a converter (12) configured to convert an input voltage (VIN) to an output voltage (VOUT). The converter includes a switch (14) that is controlled in response to an activation signal (ACT) to provide current through an inductor (16). A transition mode controller (18) provides the activation signal (ACT) based on a measure of charge derived from current through the switch and based on the current through the inductor.
