1 / 5 page Data Brief For further information contact your local STMicroelectronics sales office Rev 1 February 2006 1/5 5 STEVAL-ISA002V1 6W Single Output Supply using VIPer12A 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 Output Short Circuit Protection Thermal Shutdown Protection Meets EN55022 Class B EMI specification Applications This board is an off-line wide range single output general-purpose power supply capable of delivering up to 6W of total output power. 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: 5V @ 1.2A 12V @ 0.5A 15V @ 0.4A 24V @ 0.25A. Blue angels When working in standby, the reference board consumes less than 1W total power consumption and therefore, meets the “Blue Angel” Norm. This unit operates in burst mode when the output load is reduced to zero and normal operation will resume automatically when the power gets back to a level higher than the standby power. The output voltage remains regulated even when the board operates in burst mode. The total power consumption measured at 115Vac input with zero load at output is approximately 168mW, while at 230Vac input this value is about 248mW. At 120Vac input, a minimum load of 52mA is needed to keep the input power consumption at less than 1W. STEVAL-ISA002V1 www.st.com |
