Features Efficiency up to 96%, Non isolated, no need for heatsinks Pin-out compatible with LM78XX Linears Low profile( L*W*H=11.5*8.5*17.5mm) High voltage input range, up to 72V Short circuit protection, Thermal shutdown Non standard outputs available as specials between 3.3V~24V Low ripple and noise "L" version with 90 pins See Innoline Application Notes for use as an inverter (alternative to LM79xx Linear) INNOLINE DC/DC-Converter 0.5 AMP SIP3 Single Output Description 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 utilisation 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 for 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.
