The ISL6745EVAL2Z evaluation board is a reference design for powering high brightness white LEDs.
The ISL6745UEVAL2Z utilizes Renesas' ISL6745A, a double-ended voltage mode PWM controller, for a SEPIC converter application requiring a constant output current. It consists of separate assemblies for the driver and for the LED board, which supports as many as 21 high brightness LEDs. The LED driver board converts a universal (85V to 275VAC) AC input to a DC output rated at 300mA. The design can be further optimized for applications that do not require universal AC input. ISL6745LEVAL2Z is for 80V to 140V applications.
