8.5.2 Programming the Output Current
The devices of the TPS6126x family also support average output current regulation. An external resistor is used to program the average output current. The resistor must be connected between the RI and GND pins. When the average output current is regulated properly, the typical value of the voltage at the RI pin is 400 mV. The maximum recommended value for the regulated average output current is 100 mA. The value of the resistor R3 should be between 2 kΩ and 20 kΩ. It can be calculated, depending on the needed average output current (IOUT), using Equation 2:
Accurate regulation of the average output current only is possible if the inductor current is continuous. Please check the Inductor Selection section to calculate the required parameters for selecting an appropriate inductor.
