October 18, 2013 - Semiconductor Circuits upgrades CPZ DC-DC Converters. Models are available with a 4:1 input voltage range of 18 - 72 Vdc and up to 24 Watts output power in a DOSA standard 32nd brick DC-DC converter. These open frame modules provide up to 24 Watts of output power @ 70C & 200lfm of airflow – ideal for distributed power architecture applications, as fully regulated intermediate bus converters and, because of their size, for portable equipment use.
These modules are compliant with DOSA footprint and interface standards and provide 1500 VDC input to output isolation. Output voltages of 1.8, 3.3, 5, and 12Vdc are available. Custom versions are also being manufactured for particular industries such as Imaging, Instrumentation and Video Communications.
The CPZ product family offers conversion efficiencies up to 88% from ½ load through full load. They meet EN 60950 basic insulation requirements and are UL94 V-0 flammability rated. Safety certification by TUV is pending. The modules comply with typical industry requirements including no load operation, 2 X nominal input voltage transient and pre-biased load startup. Other features include: fixed-frequency operation, auto-restart OVP, OCP & OTP protections, UVLO, remote sense and ±10% output voltage trim using industry standard equations.
Remote ON/OFF is standard with positive or negative logic options available.
This product set features standard 1/32nd brick pinout and dimensions of 0.76” L x 0.92” W (19.3mm x 23.4mm.)
It has a maximum height of 0.35” (8.9mm) which accommodates tight card spacing with minimal airflow blockage of downstream components. Available with through hole or surface mount pins, this converter offers a very compact device with a full set of “brick” features.
