Voltage-Margining Power Supply for USB Type-C Ports in Docking Stations Reference Design

Description

This reference design allows easy system integration of a USB Type-C™ power supply that supports voltage margining. Efficiently converting power from a common 9-: 12- or 15-V adaptor to the USB Type-C port: the TPS62136 step-down converter directly accepts the digital signal of a microcontroller (MCU) to change its output voltage from the USB standard 5 V to a higher: programmable voltage. This output-voltage slew rate meets USB Type-C specifications. Especially useful for smartphone battery fast-charging applications in docking stations: this higher voltage allows more power at up to 4 A of current to be delivered across the USB Type-C cable.
