Figure 1. DOE proposed regulations vs. Level V performance for a 5V output EPS
The need to reduce active-mode power consumption is somewhat obvious. What has not been so obvious is the need to minimize power drain in standby and no-load when products are essentially doing nothing. Several studies have been performed worldwide to quantify this consumption by domestic equipment

Figure 1. Circuit diagram of the ADP2441 step-down switching regulator in a 24V nominal to 3.3V conversion
Industrial power supplies need to have very high efficiency today and often times need to be highly compact. In combination with the typical 24V rail available, many solutions utilize a switching regulator rated for 36V Vin max. Unfortunately most solutions available are non-synchronous switching regulators
