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.
