THEORY OF OPERATION The ADP2102 is a high frequency, synchronous step-down, dc-to-dc converter optimized for battery-powered, portable applications based on constant on-time current-mode control architecture with voltage feed forward to null frequency variation with line voltage, creating a ...
Page 14
ADP2102 As a result of this auto mode control technique, losses are minimized at light loads, improving system efficiency. The PSM reverse current comparator controls the entry and exit into forced continuous conduction mode. Some minor jitter is normal during ...
Page 15
SOFT START The ADP2102 has an internal soft start function that ramps the output voltage in a controlled manner upon startup, therefore limiting the inrush current. This prevents possible input voltage drops when a battery or a high impedance power ...

ADP2102 Inductor Losses Inductor conduction losses are caused by the flow of current through the inductor, which has an internal resistance (DCR) associated with it. Larger sized inductors have smaller DCR, which may decrease inductor conduction losses. Inductor core losses ...

Output Capacitor For transient applications, assume a droop of 0.1 V. Typically, it takes two to three cycles for the output to settle from a load transient because the capacitor alone supplies the load current until the loop responds. Under ...
