... In a typical pre-bias application the VPOL5A-12-SMT series converters do not draw any reverse current at start-up. The output voltage can be adjusted from 0.75 to 5.0vdc, using the TRIM pin with a external resistor. The converter can be shut down via a remote ON/OFF input that is referenced to ground. This input is compatible with popular logic devices ...

... 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 VPOL5A-12-SMT series converters are turned on if the remote ON/OFF pin is high, or left open or floating. Setting the pin low will turn the converter ‘Off’. The signal level of the remote on/off input is defined with respect to ground ...

... Layout Design Challenges. In optimizing thermal design the PCB is utilized as a heat sink. Also some heat is transferred from the VPOL5A-12-SMT module to the main board through connecting pins. The system designer or the end user must ensure that other components and metal in the vicinity of the ...
