Description

Input Voltage Range

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

outputvoltageisallthatisneeded. Multipleoutputvoltagesare

obtained just as easily. A constant current or constant power

output may be implemented with the addition of a few low cost

components.
