Input and Output Impedance
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 100 μF tantalum
capacitor with an ESR < 1 ? across the input is
recommended to ensure stability of the converter
over all operating conditions.
In many end applications, a high capacitance value
is applied to the converter’s output via distributed
decoupling capacitors. The power converter will

The positive logic version turns on when the ON/OFF
pin is at logic high and turns off when at logic low.
The converter is on when the ON/OFF pin is left
open. See the Electrical Specifications for logic

The negative logic version turns on when the pin is
at logic low and turns off when the pin is at logic
high. The ON/OFF pin can be hard wired directly to
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, with both referenced to Vin(-). A
typical connection is shown in Figure A.
Vin(-) to enable automatic power up of the converter
without the need of an external control signal.
The ON/OFF pin is internally pulled up to 5V through
a resistor. A properly de-bounced mechanical switch,
open-collector transistor, or FET can be used to
drive the input of the ON/OFF pin. The device must
be capable of sinking up to 0.2 mA at a low level
voltage of ≤ 0.8 V. An external voltage source (±20 V
maximum) may be connected directly to the ON/OFF
input, in which case it must be capable of sourcing or
sinking up to 1 mA depending on the signal polarity.
See the Startup Information section for system timing
waveforms associated with use of the ON/OFF pin.
