DER-46  
6 W peak, Multiple output PSU for DVB-T  
April 20, 2005  
1 Introduction  
This document is a prototype engineering report describing a 6 W multiple output power  
supply utilizing a TNY264P for a DVB-T Set-Top supply.  
This design is low cost and meets EMI with no common-mode choke, no X-cap, and no Y-cap.  
Cross-regulation is tight even though it has multiple outputs with no post-regulators.  
The DBV-T Set-Top has several advantages using Power Integrations’  
TinySwitch-II – TNY264P.  
No external AC/DC Adapter  
No internal DC/DC post converter  
No common mode Ferrite Core on the DC cord  
This document contains the power supply specification, schematic, bill of materials,  
transformer documentation, printed circuit layout, and performance data.
