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-pin small outline package (eSOP8).
