derating-graph (ambient temperature) description * add suffix ?l? for 90 bent pins, e.g. r-78hb5.0-0.5l en-55022 certified en-55024 certified iec/en-60950-1 certified the r-78hbxx-series high efficiency, high input voltage switching regulators are ideally suited to replace 78xx linear regulators and are pin compatible. the efficiency of up to 96% means that very little energy is wasted as heat so there is no need for any heat sinks with their additional space and mounting costs. an input voltage range of up to 8:1is unsurpassed by any other converter and allows the full stored energy utilization of standard and high voltage batteries. the fully protected output is ideal for industrial applications (especially for industry standard 24vdc bus supplies) and the l-version with 90 pins allows direct replacement f or laid-flat regulators where component height is at a premium. low ripple and noise figures and a short circuit input current of typically only 15ma round off the specifications of this versatile converter series. typical applications include telecommunication, automotive, industrial, aerospace and battery powered applications. rohs 2011/65/eu 6/6 refer to application notes specifications (refer to the standard application circuit, ta: 25c, minimum load = 10%) characteristics conditions min. typ. max. input voltage range see table 9v 72v 75v max. output voltage range (for customized parts) all series 3.3v 24v output current (see note 1) 3.3v, 5v, 6.5v, 9v, 12v, 15v 10ma 500ma 24v 6ma 300ma short circuit input current all series 15ma 25ma internal input filter 1f capacitor internal power dissipation 0.65w short circuit protection continuous, automatic recovery output voltage accuracy at 100% load 2% 3% line voltage regulation vin = min. to max. at full load 0.4% 1% load regulation 10% to 100% full load 0.3% 0.6% dynamic load stability (with output capacitor=100f) 100% <-> 50% load 75mv 100mv ripple & noise (without output capacitor) 10% to 100% full load 20mvp-p 60mvp-p continued on next page www.recom-power.com i-29 rev: 0/2015
