An excellent efficiency up to 84% allows –40°C to +85°C operation temperatures at full load. Further features include remote On/Off control and continuous short circuit protection.Typical applications for these ultra-compact converters are battery operated equipment and distributed power architectures in communication, instrumentation and industrial electronics, everywhere where space on the PCB is critical.1) where the voltage of the input power supply is wide range (voltage range ≤4:1); 2) where isolation is necessary between input and output (isolation voltage ≤1500VDC); 3) where the regulation of the output voltage and the output ripple noise are demanded. 24 Vin models: 48 Vin models: 15 mA typ.

The load shouldn't be less than 10%, otherwise ripple will increase dramatically. 2. Operation under 10% load will not damage the converter; However, they may not meet all specification listed. 3. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 4. In this datasheet, all the test methods of indications are based on corporate standards. 5. Only typical models listed, other models may be different, please contact our technical person for more details. RoHS COMPLIANT INFORMATION This series is compatible with RoHS soldering systems with a peak wave solder temperature of 300°C for 10 seconds. The pin termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin with Nickel Preplate. The DIP types are Matte Tin over Nickel Preplate. Both types in this series are backward compatible with Sn/Pb soldering systems. Microdc Professional Power Module,Inc.
