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.

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.
