 LED Driver, 350 mA, Step-Down Converter

制造商:ON

中文数据手册

产品信息

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.
  • Power Efficiency up to 94%
  • LED Drive Current up to 350 mA
  • Compatible with 12 V and 24 V Standard Systems
  • Handles transients up to 40 V
  • Single Pin Control and Dimming function
  • Drives LED Strings of up to 32 V
  • Open and Short LED Protection
  • Parallel Configuration for Higher Output Current
