High Power Density for the Latest 10W DC-DC Converter
MDWI10 SERIES MINMAX is proud to announce the new MDWI10 series of 10W Isolated/Regulated DC-DC Converters with ultra-wide input ranges in the compact 16 pin DIP package measuring only 0.94×0.54×0.31”, offering a very high power density up to 63.5W/in3. This level of integration offers system designers the opportunity to reduce overall PCB layout area or add more features into existing PCB profiles. The MDWI10 family of DC-DC converters consists of 16 models offering 9-36 or 18-75 VDC input ranges with single output models ranging 3.3–24 VDC and dual output models ±12V or ±15V delivering 10 Watts of output power. All models feature: I/O Isolation of 1500VDC; high average efficiency up to 88%; operating ambient temperature range of -40°C to +88°C ; faster start-up; fully regulated outputs with high precision; no minimum load requirement; very low no-load power consumption; shielded metal package; built-in EMI filter that meets EN55032 Class A without additional filtering required; and under-voltage/overload/short-circuit protection. All models have been qualified per the CB scheme with safety approvals to UL/cUL/IEC/EN 62368-1(60950-1)standards. All MINMAX products are Reach Compliant, RoHS Compliant, Hazardous Substance Process Management (IECQ QC 080000) and conflict Mineral free backed by a 3 Year Warranty. Documentation including datasheets, safety reports, compliance statements and 3D models are available from our website. Models are in stock and available for immediate evaluation.
