(approval pending) the jrw - series dc - dc converters are a new generation of dc/dc power modules designed for optimum efficiency and power density. the jrw provides up to 70a output current in an industry standard hal f brick, which makes it an ideal choice for small space, high current and low voltage applications. the converter uses synchronous rectification technology and innovative packaging techniques to achieve ultra high efficiency reaching 91% at 3.3v full load. the ultra high efficiency of this converter results in low power dissipation, such that for most applications a heat sink is not required. in addition, the jrw - series supports future migration of semiconductor and microprocessor supply voltages down to 1. 0v. jrw 70a single output series delivers up to 70a output current ultra high efficiency: 91% @ 3.3v full load optimal thermal performance high power density: 96 w/in3 low output voltages down to 1v: supports migration to fu ture ic and microprocessor supply voltages active load sharing option: parallel operation cost efficient open frame design applications wireless networks access and optical network equipment enterprise networks latest generation ics (dsp, fpga, asic) and microprocessor powered applications specification tightly regulated output, typical 1% monotonic start - up into pre - biased output output voltage adjustment trim +10% / - 20% load regulation 0.2% line regulation 0.2% no minimum load required ripple and noise (5hz to 20mhz bandwidth) ? rms 40mv rms (3.3v) ? peak to peak 150mv pk - pk (3.3v) operating temperature range: - 40 c to 85 c designed to meet basic insulation 1500vdc isolation voltage remote output voltage sensing protection output overcurrent and ove rvoltage protection over - temperature protection input under voltage protection options positive remote on/off logic active load sharing (parallel operation) case ground pin (base plate version) auto restart after fault shutdown industry standard half bri ck dc/dc converter, 36vdc - 75vdc (48v) input voltage range, output voltages available from 12v down to 1.0v i ii iii iv
