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. (Ambient Temperature) Typical applications include telecommunication, automotive, industrial, aerospace and battery powered applications. Output Power (%) 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. 120 100 80 60 40 20 0 Safe Operating Area -40 0 25 50 Operating Temperature (°C) www.recom-international.com 13-February-2007 85 75 100 71 1 R-78HBxx-0.5 (L) Series INNOLINE DC/DC-Converter Specifications (refer to the standard application circuit, Ta: 25°C, minimum load = 10%) Characteristics Input Voltage Range Conditions See table Min. 9 Typ. 48 Max. 72V Output Voltage Range (for customized parts) All Series 3.3 24V Output Current (see Note 1) 3.3V, 5V, 6.5V, 9V, 12V, 15V 10 500mA 24V 6 300mA Output Current Limit (Vin = 48VDC) All Series 700 1200mA Short Circuit Input Current All Series 15 25mA Internal Input Filter 1µF 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 Dynamic Load Stability (with Output Capacitor=100µF) Ripple & Noise (without Output Capacitor) 10% to 100% full load 100% <-> 50% load 10% to 100% full load Temperature Coefficient -40°C ~ +85°C ambient 0.3 ±75mV 20mVp-p 0.015%/°C Max capacitance Load 100µF Switching Frequency (See Graph) Full Load Quiescent Current Vin = 48VDC. at minimum load Operating Temperature Range 120 800kHz 1 5mA -40°C +85°C Operating Case Temperature +100°C Storage Temperature Range -55°C +125°C Case Thermal Impendance 60°C / W Thermal Shutdown Internal IC junction +160°C Relative Humidity 95% RH Package Weight 4g Case Material Non-Conductive Black Plastic Potting Material Epoxy (UL94V-0) Soldering Temperature MTBF (+25°C) .
