Pin 3 (CTRL)
This pin provides an Off function which puts the
converter into a low power mode. When the pin
is ‘high’ the converter is OFF and when the pin
is high ‘Z’ the converter is ON. There is no allo-
wed low state for this pin. Voltage to be applied
via a limiting resistor with a recommended
value of 1K for RS-05xx; 3.3K for RS-12xx; RS-
24xx and 10K for RS-48xx).
Pin 5 (NE)
This pin is used internally and must have no
external connection.

Pin 8 (Cs)
This pin provides a connection point to the main reservoir capacitor.
Additional capacitance can be added from this to pin 7. Any low ESR capa-
citor will improve ripple and noise in some measure. The benefit of this
access point over simple additional output capacitance is that it precedes
the output filter inductor. Maximum values of external capacitance will
depend on the output voltage/loading of the converter and the desired rip-
ple figure. Starting values can be in the range of 100uF.
This pin is available only for the RS-xxxx, dual output series do not have
this Cs Pin.
