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 with a recommended value of 1K for RS05xx; 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 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.
