MYMGM1R824ELA5RA MonoBK, 24A DC-DC Converter Series PRODUCT OVERVIEW The MYMGM1R824ELA5RA is miniature MonoBK called Mono Block, non-isolated Point-of-Load (PoL) DC-DC power Typical unit converters for embedded applications. The small form factor FEATURES measures only 10.5 x 9.0 x 5.0 mm. Applications include Settable output voltage from powering FPGA/CPUs, datacom/telecom systems, Distributed 0.7 to 1.8Vdc Bus Architectures (DBA), programmable logic and mixed voltage systems. Up to 24A of output current The converter has input voltage ranges of 7.5 to 15Vdc and a Quick response to load change maximum output current of 24A. Based on a fixed frequency Ultra small surface mount package synchronous buck converter switching topology, this high 10.5 x 9.0 x 5.0mm power conversion efficient PoL module features programmable High efficiency of 94.0% max. output voltage 0.7 to 1.8Vdc, On/Off control, Power Good Outstanding thermal derating performance TM signal output and PMBus ALERT output. Over current protection These converters also include under voltage lock out (UVLO), On/Off control (Positive logic) output short circuit protection and over-current protection. TM Power Good signal Moreover this converter has PMBus interface so various parameters can be handled and monitored by digital signals. High Reliability / Heat Shock Testing 700cycle (-40 to +125degC) TM PMBus interface available SIMPLIFIED APPLICATION MYMGM1R824ELA5RA Vin Vout ON/OFF +Sense PWGOOD Cout Trim RTrim GND AGND Cin MYMGM1R824ELA5RA Cin 22uF/25V x 2pcs Co 220uF/4V x 3pcs (Typical topology is shown.
