Features
Applications
This board is an off-line wide range dual output
general-purpose
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

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.

... T1. The 5Vdc output is sensed with an optocoupler possible to modify the output voltages by changing the transformer turns ratio and modifying the resistance values of R7 and R8 in the feedback loop.
