BASIC OPERATION  
LED Pin Current  
The CAT4201 is a high efficiency step-down regulator  
designed to drive series connected high-power LEDs.  
LED strings with total forward voltages of up to 32V  
can be driven with bias currents of up to 350mA.  
The LED current is set by the external RSET resistor  
connected to the regulated output of the RSET pin. An  
overall current gain ratio of approximately 2.5A/mA  
exists between the average LED current and the  
RSET current, hence the following equation can be  
used to calculate the LED current.  
During the first switching phase, an integrated high  
voltage power MOSFET allows the inductor current to  
charge linearly until the peak maximum level is  
reached, at which point the MOSFET is switched off  
and the second phase commences, allowing the  
inductor current to then flow through the Schottky  
diode circuit and discharge linearly back to zero  
current.  
LED Current (A) ≅ 2.5 x VRSET (V) / RSET (kꢀ)  
Table 2 lists the various LED currents and the  
associated RSET resistors.

The switching architecture ensures the device will  
always operate at the cross-over point between  
Continuous Conduction Mode (CCM) and Discon-  
tinuous Conduction Mode (DCM). This operating  
mode results in an average LED current which is  
equal to half of the peak switching current.
