High-efficiency 360-500W baseplate-cooled DC-DC in half-brick outline
The ICH series was designed for harsh environments service or industrial applications and incorporates features such as a 4:1 input voltage range, from 9 to 36 VDC, and a package/baseplate that allows conduction cooling for improved thermal performance including closed-box applications. These highly efficient converters, typically up to 95.7% for the 500W unit, are available in three single-output models providing regulated 12, 24, or 28 VDC. The electrical and mechanical design allows the ICH series to deliver the full power rating with a baseplate temperature of -40°C to +105°C without derating. Models with an extended temperature range down to -55°C are available. The converter is designed to meet the environmental stress limits for shock and vibration specified in MIL–STD810G throughout its service life.
Outputs are fully isolated from the input supply, allowing flexibility for various grounding requirements or for creating positive or negative outputs. Galvanic input to output isolation rated at 2250 VDC, incorporating a Basic insulation system, are standard across all models. The ICH series has been designed to meet EN60950, UL/CSA safety requirements for imbedded power modules.
Typical applications include 12 or 24V battery systems, powering motor drive systems, emergency vehicle electronics, smart grid, and heavy-duty truck solutions. The entire ICH series has no minimum load requirements. All models come with a positive logic remote On/Off control as the standard configuration, along with full protection features including input transient to 50 VDC, over temperature shutdown, output over current, and input under voltage lockout. The ICH series is scheduled for production release in January 2017.
