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.
