内容描述: [BM1050AF是组合了应对高次谐波的功率因数校正(Power Factor Correction)转换器(以下简称PFC部)与DC/DC转换器(以下简称DC/DC部)的复合LSI。DC/DC部采用准谐振方式动作,有助于实现低EMI。BM1050AF内置650V耐压启动电路。PFC部、DC/DC部均外接开关MOSFET及电流检测电阻,可实现自由度高的电源设计。PFC部采用峰值电流控制。利用带AC电压过低补偿电路的乘法器、应对负载变动的电路、最大功率补偿电路等各种保护电路,提供合适的应用方案。此外,内置跳频功能,有助于实现低EMI。DC/DC部的准谐振方式为软开关动作,有助于实现低EMI。内置脉冲串模式,可降低轻负载时的功耗。内置了软启动功能、脉冲串功能、逐周期过电流限制、过电压保护、过负荷保护等各种保护功能。与微控制器间设有通信控制用端子、外部停止端子,可提供适用于各种应用的系统方案。]
