GE Energy Power Electronics unveils lineage power hammerhead series of industrial DC-DC circuit board power conversion modules that offer wide input range, extreme temperature tolerance, and DOSA standard footprint for applications across multiple industry segments.

DC-DC converter

According to the company, the Hammerhead series offers a wide input voltage range from 18 to 75Vdc with total efficiency architecture technology that reduces power loss up to 50 per cent. Said to be designed for extreme temperature conditions of -40°C to +85°C, the cost-effective hammerhead DC-DC isolated converters aim to help OEM design engineers achieve electrical isolation, increase device reliability and accelerate new product introduction across medical, military and other industrial applications.

The standards-based DOSA footprints and compatibility with existing circuit board designs claim to shrink the size; lower the cost and improve the performance of board-mounted power modules. The hammerhead modules are said to be available in eighth-brick DOSA standard footprints with three output models rated for 12V@6A, 5V@15A or 3.3V@20A.

According to the company, Hammerhead leverages the Bell Labs heritage for reliability and quality, while also using the latest component technologies and process techniques to accelerate adoption through competitive value engineering savings opportunities. Its wide input and operating temperature range is said to be ideal for use in robotics, test and measurement equipment, medical devices, navigation systems, automotive electronics and cellular infrastructure devices.

The open frame module construction, available in both surface-mount and through-hole packages, aims to enable design engineers to minimise circuit board real estate usage, while ensuring DOSA footprint compatibility. All Hammerhead modules are said to achieve typical, full load efficiency greater than 92 per cent at VIN=24Vdc and greater than 90 per cent at VIN=48Vdc. Standard features include remote on/off, remote sense, output voltage adjustment, over-voltage, over-current and over-temperature protection. According to the company, an optional heat plate allows for external, standard eighth-brick heat sink attachment to achieve higher output current in extreme temperature environments.

The Hammerhead EHHD006, EHHD015, EHHD020 isolated DC-DC converter module samples are available now. Pricing starts at Rs.758.93 ($17) per unit for OEM quantities.
