Murata has announced the MYMGK series of miniature “Mono Block” type surface mount point-of-load (PoL) DC-DC converters. These non-isolated “Mono Block” type converters are available in two models, a 6 Amp and a 20 Amp. Each version is available with two output voltage range options. Typical applications for these converters include powering FPGAs and CPUs used in data, telecommunications, and networking communications equipment, and in equipment using distributed bus architecture.

Measuring just 9.0 x 7.5 x 5.0 mm, the 6 Amp MYMGK1R806FRSR has a programmable output voltage in the range 0.7 to 1.8 VDC from a +5 VDC input. The MYMGK00506ERSR also can deliver up to 6 Amp output in the range 0.7 to 5.0 VDC from a +12 VDC nominal input.

The 20 Amp models measure 10.5 x 9.0 x 5.6 mm and include the MYMGK1R820FRSR, operating from a +5 VDC nominal input and the MYMGK1R820ERSR, from a +12 VDC nominal. The output voltage can be programmed in the range 0.7 to 1.8 VDC.

Across the range, control signals include remote on/off and a power good indication. Safety and protection features include under input voltage lock out (UVLO), output short circuit, and output over current.

The use of increasingly compute intensive devices such as programmable logic, FPGAs and CPU 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 customer’s board size.

These 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 the MYMGK series’ high temperature operating case with its excellent thermal derating performance.
