Monotonic start-up into pre-biased output Output voltage sequencing (EZ-SEQUENCE Remote On/Off Remote Sense Over current and Over temperature protection Parallel operation with active current sharing Wide operating temperature range (-40°C to 85°C) UL* 60950 Recognized, CSA† C22.2 No. 60950-00 Certified, and VDE‡ 0805 (EN60950-1 rd 3 edition) Licensed ISO** 9001 and ISO 14001 certified manufacturing facilities TM ) Description The Austin MegaLynx series SIP power modules are non-isolated DC-DC converters in an industry standard package that can deliver up to 30A of output current with a full load efficiency of 92% at 3.3Vdc output voltage (VIN = 12Vdc). The ATH series of modules operate off an input voltage from 4.5 to 5.5Vdc and provide an output voltage that is programmable from 0.8 to 3.63Vdc, while the ATS series of modules have an input voltage range from 6 to 14V and provide a programmable output voltage ranging from 0.8 to 5.5Vdc. Both series have a sequencing feature that enables designers to implement various types of output voltage sequencing when powering multiple modules on the board. Additional features include remote On/Off, adjustable output voltage, remote sense, over current, over temperature protection and active current sharing between modules. * UL is a registered trademark of Underwriters Laboratories, Inc. † ‡ CSA is a registered trademark of Canadian Standards Association.
