POL DC-DC Converter with PMBus Interface for FPGAs


Murata Manufacturing Co., Ltd. has added products with the PMBus*2 interface to the small size, high power density, and high reliability “MonoBK™ (monoblock)” series of POL*1 DC-DC converters. This time, the company will be introducing the 24A product: MYMGM1R824ELA5RA and 16A product: MYMGM1R816ELA5RA. Production began in May 2020. Samples are now available.

The MYMGM series is equipped with an industry standard PMBus interface that makes it possible to configure, control, and monitor power supply. It also has 20% higher power density compared with the existing “MonoBK™”*3. In addition, with the downsizing of modules made possible by Murata’s original packaging technology, the mounting area of FPGAs*4, ASICs, and other kinds of LSI power supply rails was reduced, which contributes to the effective use of board space.
*1 POL: Point of Load. A DC-DC converter placed near an LSI such as an FPGA or ASIC as a dedicated power supply circuit.
*2 PMBus: Abbreviation of Power Management Bus. A communication standard for setting, controlling, and monitoring power converters.
*3 Comparison between MYMGK1R820 series and MYMGK1R812 series.
*4 FPGA: Field Programmable Gate Array LSI with circuits that can also be rewritten later on.
