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.

When operated with additional external load capacitance the rise time of the input voltage will determine the
maximum external capacitance value for guaranteed start up. The slower the rise time of the input voltage the
greater the maximum value of the additional external capacitance for reliable start up.
