External capacitance

Although these converter will work without

external capacitors, they are necessary in

order to guarantee the full parametric per-

formance over the full line load range. All

parts have been tested and characterised

using the following recommended values

and test circuit.

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 allowed low state for this pin.

Voltage to be applied via a limiting resistor

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 capaci-

tance can be added from this to pin 7. Any

low esr capacitor will improve ripple and

noise in some measure. The benefit of this

access point over simple additional output

filter inductor. Maximum values of external

capacitance will be depend on the output

voltage/loading of the converter and the

desired ripple figure. Starting values can be

in the range of 100uF.
