The final reference design board in the RDK-160 kit is the RDR-159 which has a average active efficiency of 75.1%. The no-load power consumption is far better than required, with 22 mW output at 120 V input and 28 mW output at 230 V input . This meets the most stringent requirement for 30 mW no-load for Five Star No Load voluntary program. This particular design also provides immunity to a 10 kV common-mode surge (ESD).
