These power converters have been designed to be stable with no external capacitors when used in low inductance input and
output circuits.
However, in some applications, the inductance associated with the distribution from the power source to the input of the
converter can affect the stability of the converter. A 33μ F electrolytic capacitor with an ESR < 1 ? across the input is
recommended to ensure stability of the converter over the wide range of input source impedance.
In many applications, the user has to use decoupling capacitance at the load. The power converter will exhibit stable
operation with external load capacitance up to 30,000μ F.
2.2
ON/OFF (PIN 2)
The ON/OFF pin is used to turn the power converter on or off remotely via a system signal. There are two remote control
options available, positive and negative logic, both referenced to Vin(-). A typical connection is shown in Fig. A.
