1 / 3 page Refer to Applications Notes PA-1 REV.: 0/2015 www.recom-international.com DC/DC Converter 3 YEAR warranty 3 Specifications (measured at TA= 25°C, full load, nominal input voltage and after warm-up) BASIC CHARACTERISTICS Parameter Condition Min. Typ. Max. Input Voltage Range 6.5VDC 24VDC 32VDC Output Current (2) 6mA 500mA Quiescent Current 0% Load 5mA 7mA Switching Frequency 280kHz 330kHz 380kHz Efficiency see Selection Guide Internal Power Dissipation 0.4W Output Ripple and Noise 20MHz BW limited 50mVp-p 75mVp-p Description The R-78W series offers wired 0.5A switching regulators which are ideally suited to offer a stable voltage supply without the need for a PCB for applications like high power LED lighting, battery powered systems, cooling systems, or fans. Due to the high efficiencies of up to 96% there is no need for a heat sink. The compact modules feature fully protected outputs and draw only 1mA under no load conditions. Features Switching Regulator • Efficiency up to 96%, no need for heatsinks! • Build-in Diode Protection Circuit • Low Profie (LxWxH= 11.5 x 8.5 x 17.5mm) • Continuous Short Circuit Protection • RoHS compliant • IEC/EN-60950 Certified 0.5 AMP SIP3 Single Output R-78W-0.5 Selection Guide Part Input Output Output Efficiency Max.
