1 Introduction
This engineering report describes a multiple output evaluation board designed using
TOP245P. The specification chosen is targeted towards new Set Top Box systems that
incorporate a hard disk. These systems require a peak power capability when the hard
disk is first spun-up.
Peak power operation requires magnetics and diodes specified to handle the currents at
the specified peak power point. If peak power operation is not required, designing the
supply for maximum continuous power will save additional cost.
The document contains the power supply specification, schematic, bill of materials,
transformer documentation, printed circuit layout, and measured performance data from
the prototype unit shown in Figure 1.
