The power supply application circuit of figure 3 was developed by Power Integrations to power Echelon's PLT-20 Power Line Transceiver. The universal input range of 85 to 285VAC allows use worldwide. Premiers' POL-97506 transformer meets all of the requirements as called out by Power Integration Application Design Example No. 1, this detailed application note is available from Power Integrations, Inc. The main output of this supply is a highly regulated 9.75Vdc capable of 5.4W of total continuous power. This output is then fed to a precision 3-terminal linear regulator to achieve the second 5Vdc output. Echelon's PLT-20 basic power requirements are 9.75Vdc + 0.75V @ 250mA maximum, and 5.0Vdc + 0.25V @ 80mA maximum. This leaves approximately 220mA of additional output power from the 5Vdc line to support the demands of application specific circuits and other electronics connected to the node. Below is the basic application circuit utilizing Power Integrations TOP221 switching regulator. The example circuit meets the conducted emission requirements of EN50065-1, which are significantly more demanding than those specified for North America by the FCC and Industry Canada. The component values listed are intended for reference purposes only.
