The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up. ■ No Heatsink Required SIP ■ SMD Construction ■ Toroidal Magnetics INPUT CHARACTERISTICS ■ Fully Encapsulated Parameter Conditions Voltage Range Continuous Continuous Continuous Continuous ■ No External Components ■ MTTF up to 2.4 Million hours ■ PCB Mounting operation, operation, operation, operation, 5V input types 12V input types 24V input types 48V input types MIN TYP MAX Units 4.75 11.4 22.8 45.6 5 12 24 48 5.25 12.6 25.2 50.4 V MIN TYP MAX Units 1 W %/% % mVp-p ■ Custom Solutions Available OUTPUT CHARACTERISTICS DESCRIPTION The NMF series of DC-DC Converters is used where a tightly regulated supply is required. They are ideal for situations where the input voltage is not tightly controlled. The output control pin makes the device particularly suitable for Flash PROM applications where an on/off controlled voltage source is required.
