Applications
This 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:
Q 5V/12V
Q 5V/15V
Q 5V/24V

Blue angel
The reference board consumes less than 1W total
power consumption when working in the burst
mode during standby operation and therefore,
meets Blue Angel. 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.
