TRIAC Dimmer Compatible High Brightness White LED Driver Evaluation Board


The ISL6745EVAL1Z evaluation board utilizes Renesas' ISL6745A double-ended voltage-mode PWM controller for half-bridge converters with secondary side synchronous rectification. The ISL6745 voltage mode PWM controller is a 10 Ld MSOP device.

The input of the evaluation board ranges from 36V to 75V, and the output voltage is regulated to 12V with a maximum load current of 10A. Planar transformers and inductors are used. The ISL6720A triple-output linear regulator is used to provide bias for the primary side controller and drivers.


  • Input voltage: 36V ~ 75V
  • Output voltage: 12V
  • Output power: 120W
  • Output voltage ripple: 50mV
  • Efficiency: About 90% at full load rated input voltage


  • Half-bridge converters
  • Full-bridge converters
  • Line-regulated bus converters
  • AC/DC power supplies
  • Telecom, datacom and file server power
