Description

The LD7850 is a step-down DC/DC converter, especially designed to drive power white LEDs with constant current. With capability to transfer output voltage up to 60V, the LD7850 can drive a string of up to 15 series-connected power white LEDs and ensure uniform brightness. To optimize the efficiency, the feedback voltage is set to 0.4V. This reduces the power dispassion on the current sense resistor. The other features include under-voltage lockout, over-current protection and dimming function essential for  the white LED applications.
