Quasi-Resonant Control DC/DC converter IC
准谐振控制器型DC/DC转换器ICBM1Q104FJ为所有带插座的产品提供优良的系统。为准谐振动作,实现了软开关,有助于实现低EMI。外接开关MOSFET及电流检测电阻,可实现自由度高的电源设计。本IC内置启动电路,有助于实现低待机功耗和高速启动。轻负载时内置脉冲串功能且IC消耗电流低,因此待机功耗会变小。此外,为了防止变压器的声响,实施了将常规负载时的低频声抑制到一定水平的控制,且内置瞬时短脉冲群蚊音(6kHz~20kHz)抑制功能。本IC内置软启动功能、脉冲串功能、逐周期过电流限制、过电压保护、过负荷保护、CS开路时保护等各种保护功能,安全性优异。
