MYMGK1R812 Series TM MonoBK , 12A DC-DC Converter MYMGK1R812 Series MYMGK1R812-H Series Typical unit FEATURES PRODUCT OVERVIEW Settable output voltage from TM The MYMGK1R812 series are miniature MonoBK , called 0.7 to 1.8V MonoBlock, non-isolated Point-of-Load (PoL) DC-DC power Up to 12A of output current converter for embedded applications. The small form factor Quick response to load change measures only 10.5 x 9.0 x 5.6mm. Applications include Ultra small surface mount package powering FPGA/CPUs, datacom/telecom systems, Distributed 10.5 x 9.0 x 5.6mm Bus Architectures (DBA), programmable logic and mixed High efficiency of 93.2% max. voltage systems. Outstanding thermal derating performance The converters have input voltage ranges of 4.5 to 8.0V or 8.0 Over current protection to 15.0V and a maximum output current of 20A. Based on a On/Off control (Positive logic) fixed frequency synchronous buck converter switching topology, Power Good signal this high power conversion efficient PoL module features High Reliability settable output voltage 0.7 to 1.8V, On/Off control and Power Meets CISPR 32 class B conducted emission Good signal output. These converters also include under voltage lock out (UVLO), output short circuit protection and over-current protection.
