With a new package design these converters are qualified for the higher temperatures requested by lead-free reflow solder processes. With the small footprint, these converters are the ideal solution for board level power distribution,mainly for applications in the industrial and telecom field. For automated SMD production lines the devices can be supplied in standard tape and reel package. Input Input Characteristics Characteristics Parameter Conditions Min. Typ. Max.
