Murata Smallest high power density DC-DC PoL converters for FPGA / logic designs

Murata has announced availability of the MYMGK series of miniature Mono Block type surface-mount point-of-load (PoL) DC-DC converters. The non-isolated converters are available in two models, a 6A and a 20A. Each version is available with two output voltage range options. Typical applications include powering FPGAs and CPUs used in data, telecommunications and networking communications equipment, and in equipment using distributed bus architecture. Measuring just 9mm x 7.5mm x 5mm, the 6A MYMGK1R806FRSR has a programmable output voltage in the range 0.7 to 1.8VDC from a + 5VDC input. The MYMGK00506ERSR can also deliver up to 6A output in the range 0.7 to 5VDC from a + 12VDC nominal input. The 20A models measure 10.5mm x 9mm x 5.6mm and include the MYMGK1R820FRSR, operating from a +5VDC nominal input and the MYMGK1R820ERSR, from a +12VDC nominal. The output voltage can be programmed in the range 0.7 to 1.8VDC. Across the range control signals include remote on/off and a power good indication. Safety and protection features include input under-voltage lock-out (UVLO), output short-circuit and output over-current. The use of increasingly compute-intensive devices such as programmable logic, FPGAs and CPUs is demanding highly-reliable power supplies that can quickly respond to load variations, good transient response, and a low core voltage high-current supply. The Mono Block type MYMGK series delivers fast transient response with a minimum of external output capacitors, this contributes to significantly shrinking the system board size. The highly-efficient ultra-compact converters, typically between 87.8% to 95% model and load dependent, meet the industrial and telecom requirements for size, efficiency and power density, especially in high temperature operating case with its exceptional thermal derating performance of MYMGK series, says the company.
