... Monotonic Startup with pre-bias at the output. UL/IEC/EN60950 Certified. 3. General Description 3.1 Electrical Description A block diagram of the VPOL5A-12-SIP 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 VPOL5A-12-SIP series topology is based on a non-isolated synchronous buck converter ...
