Murata Offers DC-DC Converters That Support DDR Memory Applications
Murata Power Solutions has introduced two new small form-factor point-of-load (POL) dc-dc converters that are said to deliver high-efficiency and high current density for powering DDR1, DDR2 and DDR3 memory, as well as general purpose ICs in multiple applications.
The 60A-rated VCN60BADJTU-1C and 70A-rated VCN70BADJTU-1C are said to provide high efficiency and high bandwidth solutions for a wide range of applications such as computer equipment, telecommunications hardware, test equipment and industrial automation.
Both the 60A and 70A dc-dc converters have a current density of approximately 50A/in³ and efficiency of 88% at full load. Programmable output voltage range is 0.6 to 3.5Vdc, with a typical set point accuracy of 0.5%. Input voltage is 12Vdc, and the modules have an industry standard height of 1U that can help simplify integration.
Other key features of the VCN60BADJTU-1C and VCN70BADJTU-1C include a soft start circuit, differential remote sense, power good signal, pre-bias turn on, and output enable. Comprehensive safety features include over-voltage, over-current and over-temperature protection.
The VCN60BADJTU-1C has overall dimensions of 61 x 9.5 x 31.8mm, while the VCN70BADJTU-1C measures 61 x 16.8 x 31.8mm. The pinout of both devices is identical, allowing customers to use interchangeably based on power requirements of different applications.
