Figure 1: A simplified diagram of a typical 10—20 W flyback converter for isolated off-line applications.
Over the past decade, controller-IC manufacturers have worked to reduce so-called vampire or stand-by power consumption. Organizations such as Energy Star in the US, Blue Angel in Germany, and CNIS (China National Institute of Standardization) have introduced strict stand-by power-consumption standards

Figure 2: Measured data for the Ericsson BMR450 20-Amp power module when varying input voltage from 4.5 to 14 volts and with load from zero to 20 Amps.
This case study presents the results of Ericsson’s findings of using a novel algorithm to optimize intermediate bus voltage. This approach saves significant energy and cost, while increasing reliability.
The intermediate bus architecture (IBA) was introduced to the datacom industry in the late 1990s.
