Typical applications anticipated for these converters include powering FPGAs and CPUs used in data, telecommunications and networking communications equipment, and in equipment using distributed bus architecture. Measuring 9.0 x 7.5 x 5.0 mm, the 6A 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 6A output in the range 0.7 to 5.0 VDC from a +12 VDC nominal input.

The 20A 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. Mono Block type MYMGK series delivers fast transient response with a minimum of external output capacitors. 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 high temperature operation.
