ADP1882 Overview
The ADP1882/ADP1883 are versatile current-mode, synchronous step-down controllers that provide superior transient response, optimal stability, and current-limit protection by using a constant on-time, pseudo-fixed frequency with a programmable currentlimit, current-control scheme. In addition, these devices offer optimum performance at low duty cycles by using valley currentmode control architecture. This allows the ADP1882/ADP1883 to drive all N-channel power stages to regulate output voltages as low as 0.8 V. The ADP1883 is the power saving mode (PSM) version of the device and is capable of pulse skipping to maintain output regulation while achieving improved system efficiency at light loads (see the Power Saving Mode (PSM) Version (ADP1883) section for more information).
