CAT3x & CAT4x High Efficiency LED Drivers

onsemi CAT3x & CAT4x High-Efficiency LED Drivers are step-down 7 LED drivers. These LED drivers contain a patented switching control algorithm that allows accurate LED current regulation. The CAT3x and CAT4x drivers include a single RSET that sets the full-scale LED string current up to 350mA from supplies as high as 36V. These LED drivers feature low internal power dissipation that allows the device to be housed in a tiny package without the need for dedicated heat sinking. The CAT3x and CAT4x drivers are available in CAT4101, CAT4103, CAT4109, and CAT3224 variants. These LED drivers are ideal for 12V and 24V lighting systems, LCD backlight, automotive and aircraft lighting, general lighting, and high brightness LEDs.
