RECOM DC-DC Converter, 77 to 80% Efficiency, SIP-8 Package - RS3 Series - RS3-1209S


Need a power and conversion solution to work with an unregulated supply? You're in safe hands with this DC-DC converter from RECOM. Thanks to its wide 2:1 range, it transforms an input between 9 and 18V DC to a stable, regulated output of 9V DC. This makes it a practical pick for safely powering up battery-powered equipment. With a 3W rating in a compact 21.8 (L) x 9.2 (W) x 11.1mm (H) SIP-8 package, it's a high-power-density device that's ideal for demanding industrial applications. Its efficiency of 77 to 80% means it wastes minimal energy as heat and stays cool as a cucumber using free air convection alone.
