Full-brick DC-DC converter offers high power density

Article By : Murata

Measuring 119mm x 64mm x 13.2mm and offering a 9V-36Vin range, the coverters are claimed to have the industry's highest power density.

Murata has introduced a full-brick DC-DC converter with 9V-36Vin range. The third in Murata's series of modular DC-DC converters targeted at battery and industrial systems–the first was the ICQ 250W quarter-brick, announced September 2016, and the second, ICH 360W and 500W half-brick modules announced October 2016–the ICF series utilises two output voltage options, 24V or 28V, integrated in an enclosed full-brick package. Typical applications include 12V or 24V battery systems, powering motor drive systems, emergency vehicle electronics, smart grid and truck power bus solutions.

Measuring 119mm x 64mm x 13.2mm, the converter’s package/baseplate adapts to shock and vibration described in the MIL-STD-810G while operating in the -40°C to 105°C baseplate temperature range. Modules with a temperature range down to -55°C are available on special order.

The ICF series features Murata's proprietary circuit architectures and synchronous rectification. It is EN60950, UL/CSA safety-compliant for embedded power modules. A basic insulation system provides galvanic input-to-output isolation rated at 2,250VDC across models.

The modules are specified for an efficiency up to 96.5%, monotonic startup into pre-bias loads, 400kHz fixed switching frequency, remote On/Off control (Positive or Negative logic) and external trim adjust and remote sense functions. The series has no minimum load requirement, keeps low energy consumption while the device is on standby, and ensures stable operation in low load conditions. All modules offer full protection features, including input transient to 50VDC, over-temperature shutdown, output over-current and input under-voltage lockout.

Pre-production samples of the modules are available with the series due for production release in January 2017.
