Frequently Asked Questions
What are the input and output voltage specifications of the DCP020503P?
The DCP020503P accepts a 5V nominal input voltage (4.5V minimum, 5.5V maximum) and provides an isolated 3.3V output at up to 2W continuous power, making it suitable for 5V-to-3.3V isolated bus conversion.
What is the efficiency rating of the DCP020503P?
The DCP020503P achieves a typical efficiency of 74% at nominal 5V input and full 2W load, meaning approximately 74% of input power is delivered to the output, with the remainder dissipated as heat in the module.
What safety approvals does the DCP020503P carry?
The DCP020503P carries UL (Underwriters Laboratories) approval, certifying it meets North American safety standards for isolated power conversion, making it suitable for use in industrial, commercial, and certain medical ancillary power applications.
What package does the DCP020503P use?
The DCP020503P is packaged in a 7-pin DIP (Dual In-line Package) through-hole form factor, offering easy hand or wave-soldering for prototype boards and industrial applications requiring reliable mechanical attachment.
What is the typical application for the DCP020503P?
The DCP020503P is typically used to power isolated serial communication interfaces (CAN, RS-485, RS-232), isolated ADC front-ends, and isolated gate drivers in industrial automation, data acquisition, and test equipment where galvanic isolation prevents ground loops and noise injection.
