Description
RAA230161 (USB Voltage Supply) is the power supply IC for the power supply application with USB power delivery.
This IC provide 5.3V to 20V power supply. Power MOSFETs are included and maximum output power is 60W (20V,
3A). Various protection circuits are included to design safe system easily. The output voltage can be selected by I2C and
the IC status can be monitored. The design of the power supply system with USB power delivery become easy by this
IC.
