Description

The RD5 reference design board is an example of a very low cost production worthy power supply design using the TOPSwitch 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 basic design that can be easily modified to fit a particular application. In most cases, a minor change to the transformer for a different output voltage is all that is needed. Multiple output voltages are obtained just as easily. A constant current or constant power output may be implemented with the addition of a few low cost components.
