1 / 3 page I-1 REV.: 0/2016 www.recom-power.com DC/DC Converter 3 YEAR warranty 3 Specifications (measured @ ta= 25°C, full load, nominal input voltage and after warm-up) BASIC CHARACTERISTICS Parameter Condition Min. Typ. Max. Nominal Input Voltage 24VDC Input Current @ no load 1.5mA Minimum Load (3) 2% Operating Frequency 570kHz Output Ripple and Noise 20MHz bandwidth 3.3, 5, 9Vout 12, 15Vout 50mVp-p 70mVp-p Description The R-78E series is a switching regulator module that has been designed to offer all the advantages of a switching regulator (high efficiency, wide input range, accurate output voltage regulation) but with a low cost for production quantities. Due to the R-78E’s high efficiency of up to 95% no heat-sink is required. The compact TO-220 compatible SIP3 package measures only 11.6 x 8.5 x 10.4mm, so it saves precious board space. Features Switching Regulator • Low Cost Switching Regulator • High Start-up Current Capability • Efficiency up to 95% • Short Circuit Protection • Pin Compatible with 78 Series Regulators • Non Isolated DC-DC Converter • IEC/EN60950-1, Am2 Certified 500mA SIP3 Single Output R-78E-0.5 Selection Guide Part Input Output Output Efficiency Max.

Note2: test by minimum input and constant resistive load. Notes: Note3: recommend to use with more than 2% load, if not, the ripple of the product may exceeds the specification, but doesn’t affect the reliability of the product. |
