The efficiency of up to 96% means that very little energy is wasted as heat. Full power is available over a temperature range of -40°C up to 70°C without the need for heatsinks with their additional space and mounting costs. A high input voltage of up to 32VDC and output voltages from 1.2V up to 15V, low ripple and noise figures and a short circuit input current of typically only 10mA round off the specifications of this versatile converter series. Features Switching Regulator • Efficiency Up To 96%, No Heatsinks Required • 2A Continuous Output Current • Vin Up To 32V • Vout: 1.2V - 15V • Wide Operating Temperature -40°C to +70°C at Full Load • S/C And Over-temperature Protection • Pin Compatible With TO220 Linear Regulators • Positive To Negative 2.0 Amp SIP3 Single Output R-78B-2.0 Selection Guide Part Input Output Output Efficiency @ full load Max.
