Part Details:

STEVAL-ISA004V1 VIPer22A-E dual-output evaluation board with 90 to 264 VAC input and 10 W output Data Brief Features Switch-mode general-purpose power supply Input: 90 to 264 VAC 50/60 Hz Output: 12 V @ 0.42 A and 5 V @ 1 A Burst-mode operation in standby for Blue Angel operation Current mode control Switching frequency: 60 kHz STEVAL-ISA004V1 75% efficiency Auxiliary undervoltage lockout with hysteresis Output short-circuit protection Thermal shutdown protection Meets EN55022 Class B EMI specification Description This evaluation board is an offline, wide-range, VIPer22A-E dual-output power supply with a switching frequency of 60 kHz and is set up for secondary regulation with an optocoupler. One output delivers 5 V at 1 A and a second output delivers 12 V at 0.42 A, making for a total output power of 10 W. The evaluation board meets Blue Angel Norms, consuming less than 1 W total when working in standby mode. The board operates in burst mode when both the output loads are reduced to zero and the output voltages still remain regulated.
