ISL6745EVAL1Z, Evaluation Board Using ISL6745 48V to 12V, 120W Half-Bridge Power Supply for Telecom Applications
Projeto de referência por: Renesas Electronics
ISL6745EVAL1Z, Evaluation Board is a low cost, high performance LED driver with power factor correction function, and is compatible with the widely used wall dimmers. It uses Renesas' voltage mode PWM controller ISL6745A 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
