CAT4201 Datasheet (Catalyst Semiconductor) - 350mA High Efficiency Step Down LED Driver

CAT4201, 350mA High Efficiency Step Down LED Driver

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 350mA from supplies as high as 36V.
