CAT4201
350 mA High Efficiency
Step Down LED Driver
Description
The CAT4201 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 CAT4201 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.
