概要

The ISL6745ALEVAL3Z is a low cost, high performance LED driver with power factor correction (PFC) function that is compatible with widely used wall dimmers. It uses Renesas' ISL6745A voltage mode PWM controller to operate a SEPIC converter in discontinuous conduction mode (DCM).

The ISL6745A is a low-cost, double-ended voltage-mode PWM controller designed for half-bridge and full-bridge power supplies and line-regulated bus converters. It provides precise control of switching frequency, adjustable soft-start and overcurrent shutdown.

The evaluation board design gives high flexibility on both the input side and output load. With the same circuit configuration, it works well with and without a triac dimmer.
