The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up. ■ Internal SMD Construction ■ Toroidal Magnetics INPUT CHARACTERISTICS ■ Fully Encapsulated Parameter Conditions MIN TYP MAX Units Voltage Range Continuous operation, 5V input types Continuous operation, 12V input types 4.5 10.8 5 12 5.5 13.2 V MIN TYP MAX Units 1 W 1.2 15 15 10 10 10 75 %/% ■ No External Components Required ■ MTTF up to 1.9 Million hours ■ PCB Mounting ■ Custom Solutions Available DESCRIPTION The NMD series of DC-DC converters are ideally suited to applications where a potential difference exists between loads, eg motor control circuits. The twin outputs offer cost and space savings by consolidating two DC-DC Converters into one package. All of the rated power may be drawn from a single output provided the total load does not exceed 1 Watt.
