5.5-28V 2ch Synchronous Buck converter(controller) with Built-in Linear Regulator BD9528AMUV

本LSI是以大电流输出能力实现从宽输入电压范围(5.5~28V)到低输出电压(1.0V~5.5V)的开关稳压器控制器。通过使用外置N-MOSFET开关晶体管能够实现高效率同步整流开关稳压器。通过采用ROHM独创的H3RegTM控制模式,能够实现业界最快的过渡响应特性。另外,为了改善轻负载时的效率采用SLLM(Simple Light Load Mode),对于宽范围负载均可实现高效率。具有软起动功能、频率可变功能、带定时锁存器的短路保护电路功能、REF同步功能,最适于作为笔记本PC的主电源控制器使用。
