STPD01PUR

STPD01PUR is a programmable synchronous buck converter for USB power delivery. It is suitable to provide power supply in applications following USB power delivery specifications. The device provides those voltages required by USB power delivery systems as stated in USB PD 3.0 spec up to 60W output power (20V, 3A). 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 safety of the complete system. Typical applications are AC adapters, USB hubs, PC monitors, Smart TV, USB-PD power distribution.
