说明

喜马拉雅系列稳压器IC和电源模块让您的电源方案工作温度更低、设计更简单。MAXM17545为使用简单的降压型电源模块,包括开关电源控制器、两个n沟道MOSFET功率开关、一个完全屏蔽电感以及补偿元件,采用薄型、热效率、系统级封装(SiP)。器件工作在4.5V至42V宽输入电压范围,提供高达1.7A连续输出电流,在0.9V至12V输出电压范围具有优异的线性和负载调整率。器件只需5个外部元件即可构成完整的总体电源方案。高度集成大大降低设计复杂度、制造风险,提供真正的即插即用电源方案,缩短上市时间。

器件可在脉宽调制(PWM)、脉冲频率调制(PFM)或非连续传导模式(DCM)控制方法下工作。

MAXM17545采用薄型、高散热、紧凑、29引脚、9mm x 15mm x 2.8mm SiP封装,降低封装功耗,增强效率。封装很容易焊接到印刷电路板,适用于自动化电路板组装。器件工作在-40°C至+125°C工业级温度范围。
