双电流模式PWM控制器

CD5034双电流模式PWM控制器可实现两个独立的正激/有源钳位DC-DC直流转换器或由两个交错功率级组成的单一大电流转换器所需的所有功能。两个控制器180°异相工作，从而减少输入纹波电流。\nCD5034包括一个启动稳压器，可在高达100V的宽输入电压范围内工作，复合(双极+CMOS)栅极驱动器可提供2.5A峰值灌电流。有源钳位门驱动器的可调死区时间和可调最大PWM占空比减少了对初级侧MOSFET开关的应力。其他功能包括可调输入欠压锁定、逐周期电流限制、过载打嗝模式、可调重启延迟、PWM斜坡补偿、软启动和外同步功能。 •双独立PWM电流模式控制器\n•集成高压启动调节器\n•复合2.5A主输出栅极驱动器\n•单电阻振荡器设置，最大频率可设置到\n2MHz\n•同步振荡器\n•用于P沟道MOSFET的有源钳位栅极驱动器\n•可调栅极驱动重叠时间\n•可调最大占空比\n•最大占空比可达76%（典型值）\n•限流打嗝模式时间可调\n•集成斜坡补偿\n•可调输入欠压锁定\n•独立可调节软启动\n•与光电耦合器晶体管的直接接口\n•过热保护\n•封装形式：TSSOP20;
