General Description
The CN5728 is a current regulation integrated circuit operating from an input voltage of 2.85V to 6V, the constant output current can be set up to 1.5A with an external resistor. The CN5728 is ideal to be used to drive LED. The on-chip power transistor and current sense block greatly reduce the external component count.
