CAV4201  
350 mA High Efficiency  
Step Down LED Driver  
Description  
The CAV4201 is a high efficiency step−down converter optimized  
to drive high current LEDs. A patented switching control algorithm  
allows highly efficient and accurate LED current regulation. A single  
RSET resistor sets the full scale LED string current up to 350 mA from  
supplies as high as 36 V.

The switching architecture of the CAV4201 results in extremely low  
internal power dissipation allowing the device to be housed in a tiny  
package without the need for dedicated heat sinking. The device is  
compatible with switching frequencies of up to 1 MHz, making it ideal for  
applications requiring small footprint and low value external inductors.  
Enable, analog dimming and LED shutdown control is provided via a  
single input pin, CTRL. Additional features include overload current  
protection and thermal shutdown. The device is available in the low  
profile 5−lead thin SOT23 package and is ideal for space constrained  
applications.
