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高达12W的 连续

输出功率,峰值输出功率更可达18W。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,在功 率管截止时,内部电路将功率管反向偏置,

直接利用了双 极性晶体管的CB高耐压特性,大幅提高功率管的耐电压 能力直到700V的高压,这保证了功率管的安全,VCC达

到9.8V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

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。

特点

● 内置700V高压功率开关管,极少外围器件
