Features
Applications
This evaluation board is an off-line wide range
dual output general-purpose power supply
capable of delivering a total output power up to
6W. In low load condition, it operates in the
automatic burst mode while in an overvoltage
condition it will operate in hiccup mode. Other
output voltages can easily be achieved by
changing the transformer and a few components
on the board, as shown in the application note.
Transformers are readily available for the following
configurations:

Rev 1
Description
The evaluation board consumes less than 1W
total power consumption when working in the
burst mode during standby operation and
therefore, meets Blue Angel norm. Table 2 below
outlines the total power consumption measured
on the reference board at different line voltages
with zero loads at both the outputs. The output
voltages remain regulated when operating in burst
mode condition.
