Quarter brick DC/DC Converter from Murata Power Solutions

The new converter has an open frame design and an industry standard package measuring 58.4mm x 36.8mm x 10.2mm high. Designed for printed circuit board mounting, the module is suitable for use across its -40ºC to 85ºC. For applications where additional thermal performance is a critical design criteria, an optional baseplate can be provided.

The HPQ series has a wide voltage input range of 36VDC to 75VDC. An advanced planar magnetics design provides full magnetic and optical isolation with basic insulation up to 2250V. High efficiency to 90% is achieved through the use of a synchronous rectifier topology and the converter’s fixed output voltage is regulated to within ±1% and may be trimmed within ±10% of nominal output. Excellent ripple and noise performance enable the HPQ series to meet the requirements of the latest power hungry CPUs, ASICs, programmable logic devices and FPGAs.

External remote on/off control that may use either positive or negative polarity is provided for applications needing controlled start-up or shutdown. Remote sense inputs compensate for resistive line drops at high currents. A number of self-protection design features include: input under-voltage lockout; input/output over voltage protection; over-temperature shutdown using an onboard temperature sensor; ‘hiccup’ output over-current protection with auto-restart; and start-up in pre-biased load conditions.

The HPQ series is fully RoHS compliant and is designed to meet the requirements of UL/EN 60950-1, CSA-C22.2 No. 60950-1 safety approvals, and RFI/EMI conducted /radiated emission compliance to FCC part 15.
