The device provides those voltages required by USB power delivery systems as stated in USB PD 3.0 spec up to 60 W output power (20 V, 3 A). The different levels of output voltage and current limitation can be set dynamically through I2C interface. Overvoltage, overcurrent and overtemperature protections are included in the device. A programmable watchdog improves the robustness and the safety of the complete system. Finally, the devi...
