Part Details:

STEVAL-ISA002V1 6W single output supply evaluation board using VIPer12A Data Brief Features Switch mode general purpose power supply Input: 85 to 264 VAC @ 50/60 Hz Output: 12V @ 0.5A Output power (peak): 6W Burst mode operation in standby for blue angel operation Switching frequency 60 kHz 75% efficiency Auxiliary undervoltage lockout with hysteresis STEVAL-ISA002V1 Output short circuit protection Thermal shutdown protection Description Meets EN55022 Class B EMI specification When working in standby, the valuation board Applications consumes less than 1W total power consumption and therefore, meets the "Blue Angel" norm. This This evaluation board is an off-line wide range unit operates in burst mode when the output load single output general-purpose power supply is reduced to zero and normal operation will capable of delivering up to 6W of total output resume automatically when the power gets back power. In low load condition, it operates in the to a level higher than the standby power. The automatic burst mode while in an overvoltage output voltage remains regulated even when the condition it will operate in hiccup mode. board operates in burst mode. The total power consumption measured at 115Vac input with zero Other output voltages can easily be achieved by load at output is approximately 168mW, while at changing the transformer and a few components 230Vac input this value is about 248mW. At on the board, as shown in the application note. 120Vac input, a minimum load of 52mA is needed Transformers are readily available for the following to keep the input power consumption at less than configurations: 1W. 5V @ 1.2A 12V @ 0.5A 15V @ 0.4A 24V @ 0.25A.
