Compact DC/DC coverters have high power density
The MYMGK series of miniature 'Mono Block' type surface mount Point-of-Load (PoL) DC/DC converters has been announced by Murata. These non-isolated 'Mono Block' type converters are available in two models, a 6 and 20A. 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 9.0x7.5x5.0 mm, the 6A MYMGK1R806FRSR has a programmable output voltage in the range 0.7-1.8VDC from a +5VDC input. The MYMGK00506ERSR also can deliver up to 6A output in the range 0.7-5.0VDC from a +12VDC nominal input.
The 20A models measure 10.5x9.0x5.6mm 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 0.7-1.8VDC.
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 high reliable power supplies that have can quickly respond to load variations, good transient response, a low core voltage high current supply. 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%-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 excellent thermal derating performance of MYMGK series.
