Conclusion

A 5 W CV-CC optoless adapter demonstration board using the ALTAIR05T-800 device was

presented and the results show that very good performance can be obtained using this new

device.

The unique “all-primary sensing” feedback for both constant voltage and constant current

eliminates the need for the optocoupler, the secondary voltage reference, as well as the

current sensor, making the IC suitable for AC-DC chargers for mobile phones and other

portable equipment, as well as any adapter requiring tight tolerance from both CV and CC

regulation.

The ALTAIR05T-800 is capable of meeting the most restrictive worldwide standards for

efficiency and power consumption at no-load.

The embedded protection features of this new device and the 800 V power section

considerably increase the safety and reliability of the end product.
