... Monotonic Startup with pre-bias at the output. UL/IEC/EN60950 Certified. 3. General Description 3.1 Electrical Description A block diagram of the VPOL16A-12-SMT 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 VPOL16A-12-SMT series topology is based on a non-isolated synchronous buck converter ...

... The remote ON/OFF input feature of the converter allows external circuitry to turn the converter ON or OFF. Active-high remote ON/OFF is available as standard. The VPOL16A-12-SMT are turned on if the remote ON/OFF pin is high(=Vin), or left open. Setting the pin low(<0.4Vdc) will turn the converter ‘Off’. The signal level of the remote on/off input is defined with respect to ground ...
