Description
The RD6 reference design board is an example of a low cost
production worthy design for a self-powered, 4-port USB hub.
The design is a complete solution for powering hubs found in
products such as monitors and printers. A total of 15 W of
power is delivered through two outputs. The main output
supplies 3 A at 5 V. This meets the USB specification of
500 mA for each port (4 port total) with additional power
available for a 5 V hub controller. A second 3.3 V (100 mA)
output provides power for low voltage hub controllers.
The RD6 utilizes the TOP223Y member of the TOPSwitch-II
family of Three-terminal Off-line PWM Switchers from
Power Integrations. It is intended to help TOPSwitch users to
develop their products quickly by providing a production
ready design which needs little or no modification to meet
system requirements.
