Electronika enterprises provides a new p series [pa, pb, pc and pd] of high power dc dc converters manufactured by pico electronics inc, usa. Input voltage range:-from 18 380 v dc, while maintaining a regulated output. It gives 3.3 to 350 v dc outputs. Its maximum output power is 100 w. The availability of dual isolated outputs, small size, and the capability of parallel operations as standard features should reduce the design and component costs, while the fixed frequency operation helps parallel connections for higher power requirements. It is available in single and dual isolated output models. These are fully safeguarded for over voltage, over temperature and continuous short circuit protection. It has a fixed frequency of 100 khz. Its operating temperature is minimum 0°c ambient and maximum +85°c base plate temperature. It storage temperature ranges from55[c to +105[c.They offer high density and high efficiency design. It finds application in thermal considerations, output voltage trimming, parallel operation, use of the shutdown pin, noise reduction and overload protection.
