Control Pin Input Current: Voltage Set Point Accuracy with external input/output capacitors refer to recommended test circuit: Control Pin (CTRL) Input Current, control voltage applied via 1K resistor, output voltage must reduce to 0V:
10mA
typ. 1% max. 2%
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 with a recommended value of 1K for RSO-05xx; 3.3K for RSO-12xx; RSO-24xx and 10K for RSO-48xx. Pin 5 (NE) This pin is used internally and must have no external connection.
typ. 3mA max. 6mA
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 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 ripple figure. Starting values can be in the range of 100uF.
