Vishay Sip11206中间母线转换(IBC)方案
Vishay公司的Sip11206是半桥中间母线转换器(IBC)初级控制器,工作电压36V到75V,能经受住100ms 100V的瞬变电压,用来控制和驱动半桥转换器中的低边和高边开关器件,并集成了± 1.6 A低边和高边MOSFET驱动器, 开关振荡器频率可从200 kHz 到1 MHz编程,非常适合于绝缘式应用如通信,数据通信,以及其它需要IBC架构和标准母线电压如48V到更低电压如24V,12V,9V或5V的转换.本文介绍了Sip11206的主要特性,方框图,典型应用电路以及采用Sip11205或Sip11206的IBC演示板的初级,次级和基板的电路图和所用元件列表.
SiP11206 is a controller for the primary side of a half-bridge intermediate bus converter (IBC). It is ideally suited for isolated applications such as telecom, data communications and other products requiring an IBC architecture and conversion of standard bus voltages such as 48 V to a lower intermediate voltage, where high efficiency is required at low output voltages (24 V, 12 V, 9 V or 5 V).
Designed to operate within the telecom voltage range of 36 V to 75 V and withstand 100 V transients for a period of 100 ms, the IC is designed for controlling and driving both the low- and high-side switching devices of a half-bridge converter.
