ACDC for LED

Hi

We want to find a suitable ACDC chip for LED application.

The specifications are as follows:

1, Input voltage: 220VAC.           

2, The constant current output current is about 150 mA or 70 mA (adjustable), load power is about 15 watts or 7 watts.           

3, non isolation

Could you help to suggest?

Thank you,

Jerry
