In the adjustable output-voltage version, TPS62400-Q1 device, one can set the converter 1 default output voltage with an external resistor network on the DEF_1 pin, which operates as an analog input. In this case, one can set the output voltage in the range of 0.6 V to VIN V. The FB1 pin must directly connect to the converter 1 output voltage VOUT1. It feeds back the output voltage directly to the regulation loop.
One can also change the output voltage of converter 1 with the EasyScale serial Interface. This makes the device very flexible for output-voltage adjustment. In this case, the device uses an internal resistor network.
In the fixed default output voltage version, TPS62402-Q1 for example, the DEF_1 pin configuration is as a digital input. Converter 1 defaults to 1.2 V or 1.8 V, depending on the level of the DEF_1 pin. If DEF_1 is low, the default is 1.2 V; if high, the default is 1.8 V. With the EasyScale interface, one can change the output voltage for each DEF_1 pin condition (high or low).
