General Description
A block diagram of the AC100 series converter is shown in Figure 1. Extremely high efficiency power conversion is achieved through the use of synchronous rectification and drive techniques. Essentially, the powerful AC100 series topology is based on an isolated synchronous forward converter. The control loop is optimized for unconditional stability, fast transient response and a very tight line and load regulation. The output voltage can be adjusted from +5% to –5%, using a variable resistor.
