PIN FUNCTIONS  
IN is the power supply. During normal operation the  
device draws a supply current which is almost constant.  
A very brief interval of non-conduction will occur at the  
switchingfrequency.Thedurationofthenon-conduction  
interval is set by the internal non-overlapping  
“break-before-make” timing. IN should be bypassed  
with a 1µF to 4.7µF low ESR (Equivalent Series  
Resistance) ceramic capacitor.  
resistor network (400k). The feedback network will  
result in a reverse current of 10µA to 20µA to flow back  
through the device to ground.  
Wheneverthedeviceistakenoutofshutdownmode,the  
output voltage will experience a slew rate controlled  
power-up. Full operating voltage is typically achieved in  
less than 0.5 msec.  
For filtering, a low ESR ceramic bypass capacitor (1µF)

injected back into the power supply.

5 devices.  
SHDN is the logic control input (Active LOW) that places  
the device into shutdown mode. The internal logic is  
CMOS and the pin does not use an internal pull-down  
resistor. The SHDN pin should not be allowed to float.  
FB (CAT3200 Only) is the feedback input pin. An output  
divider should be connected from OUT to FB to program  
the output voltage.  
CPOS,CNEGarethepositiveandnegativeconnections  
respectively for the charge pump flying capacitor. A low  
ESR ceramic capacitor (1µF) should be connected  
between these pins. During initial power-up it may be  
possibleforthecapacitortoexperienceavoltagereversal  
and for this reason, avoid using a polarized (tantalum or  
aluminum) flying capacitor.  
PGND (CAT3200 Only). Is the same as GND for the  
CAT3200-5 except for the internal reference connection  
to SGND.  
SGND (CAT3200 Only) Ground pin for the internal  
reference. The CNEG connection is switched to this pin  
during the normal charge pump operation.  
OUT is the regulated output voltage to power the load.  
During normal operation, the device will deliver a train of  
current pulses to the pin at a frequency of 2MHz.  
Adequate filtering on the pin can typically be achieved  
through the use a low ESR ceramic bypass capacitor  
(1µF to 4.7µF) in close proximity to the OUT pin. The  
ESR of the output capacitor will directly influence the  
output ripple voltage.  
When the shutdown mode is entered, the output is  
immediatelyisolatedfromtheinputsupply,however,the  
output will remain connected to the internal feedback
