BM1C101F
Power Factor Correction and Quasi-Resonant DC/DC converter IC

作为功率因数矫正转换器(Power Factor Correction: PFC)+准谐振(Quasi-Resonant: QR)DC/DC转换器的多转换器IC,BM1C101F为带插座的产品提供优良的系统。本产品内置650V耐压启动电路/X-Cap放电功能,有助于实现低待机功耗。PFC部采用电压控制方式的临界模式(BCM),可通过Zero Current Detection(ZCD)降低开关损耗和噪声。通过电阻进行零电流检测,因此无需ZCD用辅助绕组,可减少偏置部电路的零件数量,降低损耗。DCDC部采用准谐振方式。此方式实现了软开关,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。轻负载时通过启动脉冲串功能提高效率。内置双系统PFC输出过电压保护功能。内置任意负载的PFC ON/OFF功能,可降低待机功耗。内置丰富的保护功能(VCC过电压保护、外部锁存保护、掉电保护、软启动功能、逐周期过电流限制、过负荷保护等)。
