Circuit operation
(1) The basic application examples are shown in Fig.2.
The externally installed parts are only the input and
output smoothing capacitors.
(2) Switching on and off the output voltage is allowed.
The output can be switched off by making pin 4 to
be open (high impedance). (See Fig.3)
(3) Fine adjustment of the output voltage is allowed.
The fine adjustment of output voltage can be
performed from pin 6 via the resistor by connecting
the output terminal (pin 2) or GND.(See application
example3)
Application example
Application example 1 : DC / DC converter with a protection circuit
Application example 2 : Output ON / OFF control

Fig.6
A resistor to secure the rise of output at power on. The resistance to be selected depends on the input voltage.
This is a standard application. Because the control current fluctuates with variations in circuits and components,
set the control current by adding a sufficient margin to the normal current level.
