产品介绍





概述 高性能电流模式PWM控制器,专为高性价比AC/DC 转换器设计,在85~265V的宽电压范围内提供最高可达

12W/15W/18W的连续输出功率。优化的高合理性电路设 计结合高性价比的双极制作工艺,最大程度上节约了产

品 的整体成本。该电源控制器可工作于典型的反激电路拓扑 中,构成简洁的AC/DC转换器,IC内部启动电路被设

计成 一种独特的电流吸入方式,可利用功率开关管的本身放大 作用完成启动(开关管Ic对Ib的放大),这显著地

降低了 启动电阻的功率消耗,而在输出功率较小时,IC将自动降 低工作频率,从而实现了极低的待机功耗,

VCC达到 9.9V/12V/22.5V时,芯片内部会启动过压保护,限制输出 电压上升可防止光耦或反馈电路损坏引起的输

出电压过 高,IC内部还提供了完善的防过载,防饱和功能,可实时 防范过载、变压器饱和、输出短路等异常状况,

提高了电 源的可靠性。IC内部还集成了带有迟滞的温度保护功能, 在芯片过热时关断输出。电流限制可由外部器

件Rs设定, 根据不同功率要求可适当微调Rs。
