Description

• Parameters: 汽车应用的限流可调、降压型DC-DC控制器
• Description: SD45237是一款微型MSOP-10封装、可调限流的DC-DC控制芯片,用于驱动外部N沟道MOSFET实现降压转换。芯片内部包括误差放大器、振荡器、电流比较器、斜坡补偿、电流采样、逻辑驱动等模块,电流误差放大器的内部集成,使得该芯片可以实现恒压恒流控制。峰值电流模式的PWM控制环路以及补偿网络的外部可调,使该芯片可在宽负载范围内提供稳定的输出电压;电流采样端的引出,通过设定采样电阻值,可以简单、精确地实现限流值的外部调节。 内部峰值限流以及短路保护、过温保护避免了芯片以及外部器件在超负荷负载或者温度过热时受到损坏;120KHz的频率以及微型MSOP-10封装,最大限度的减小了整体解决方案的占板面积。
• Features: ±2%的反馈电压精度 限流值外部可调 40V的最高工作电压 120KHz的开关频率 拥有专利技术的电压电流环路控制 拥有专利技术的输出电压导线电阻损耗补偿 内置软启动 输入欠压锁定 过温保护 纤小型MSOP-10封装
• Applications: Charging
