Capacitor Selection  
Diode Selection  
Low ESR (equivalent series resistance) capacitors should  
be used at the output to minimize the output ripple voltage.  
The low ESR and small package options available with  
multilayer ceramic capacitors make them excellent choices.  
The X5R and X7R capacitor types are preferred because  
they retain their capacitance over wider voltage and  
temperature ranges than the Y5V or Z5U types. A 1.0 mF or  
2.2 mF output capacitor is recommended for most  
applications.  
The voltage rating of the output capacitor C2 depends on  
the number of LEDs driven in series. A 10 V ceramic  
capacitor is recommended when driving two LEDs. A 16 V  
ceramic capacitor is recommended when driving 3 or 4  
LEDs.  
Schottky diodes, with their low forward voltage drop and  
fast switching speed, are the ideal choice for high efficiency  
applications. Table 7 shows several different Schottky  
diodes that work well with the CAT32. Make sure that the  
diode has a voltage rating greater than the output voltage.  
The diode conducts current only when the power switch is  
turned off (typically less than one−third the time), so a 0.4 A  
or 0.5 A diode will be sufficient for most designs.

LED Current Programming  
The LED current is programmed with a single resistor  
connected to the RSET pin. The RSET pin is internally  
regulated to 100 mV, which sets the current flowing out of  
this pin, ISET, equal to 100 mV/RSET. The CAT32 regulates  
Kemet  
Low profile ceramic capacitors with a 1 mm maximum  
height/thickness are available for designs height  
requirements. Ceramic capacitors also make a good choice  
for the input capacitor, which should be mounted as close as  
possible to the CAT32. A 2.2 mF or 4.7 mF input capacitor is  
recommended. Table 6 shows a list of several ceramic  
capacitor manufacturers. Consult the manufacturers for  
detailed information as new products and package options  
are introduced regularly.
