BD7672BG
PWM控制器型 AC/DC驱动器用 DC/DC转换器IC

AC/DC用PWM控制器型DC/DC转换器BD7672BG为所有存在插口的产品提供很好的系统。绝缘、非绝缘均可对应,可轻松设计各种形式的低功耗转换器。外接开关用MOSFET及电流检测电阻,可实现自由度高的电源设计。通过峰值电流控制,可进行逐周期电流限制,发挥带宽和瞬态响应的优异性能。BD7672BG内置了软启动功能、脉冲串功能、逐周期过电流限制、VCC过电压保护、过负荷保护等各种保护功能。备有外部锁存端子(COMP端子),可通过外部信号停止锁存(OFF)。此功能可用于过热保护及输出过电压保护等。开关频率固定为65kHz。内置跳频功能,有助于实现低EMI。
