CN5711
1.5A High Brightness LED Driver IC
Product Profile
   Application Note
 
General Description:
The CN5711 is a current regulation integrated circuit operating from an input voltage of 2.8V to 6V, the constant
output current can be set up to 1.5A with an external resistor. The CN5711 is ideal for driving LED.The on-chip
power MOSFET and current sense block greatly reduce the number of external component count. The CN5711
adopts the temperature regulation instead of temperature protection function, the temperature regulation can
make the LED being turned on continuously in case of high ambient temperature or high voltage drop.Other
features include chip enable,etc.
CN5711 is available in thermally-enhanced 8-pinsmall outline package (SOP8).
