【应用】内部集成功率MOSFET的DC-DC转换器SCT2331TVBR用于低压电源模块,开关频率400kHz
电源模块是电压转换的设备之一,在工业自动化、轨道交通等行业得到广泛的应用,可以为后端电路提供稳定、高效率的供电方案。同时电源模块还具有使用维护方便、节省成本、时间等优势,得到越来越多的应用。
在某低压电源模块的设计中需要取一路辅助电源给MCU等供电,要求可以输出3.3V,输出纹波小,推荐一颗芯洲科技的DC-DC转换器SCT2331TVBR,具有宽工作电压范围等特点。
芯洲科技的SCT2331TVBR应用于低压电源模块的设计中有以下特点:
1、开关频率固定在400kHz支持强制脉宽调制(FPWM)模式,有利于实现轻负载条件下的小输出纹波。
2、输入电压范围为3.8V~32V,具有输入电压范围宽的特点,可以满足低压18V-24V的输入电压要求。
3、最大可以支持3A的连续输出电流,可以满足MCU等器件的电流要求。
4、内部集成了83mΩ上端MOSFET和43mΩ下端MOSFET,可以节省掉外部场效应管,有利于节省PCB空间和降低成本。

如何为降压应用选择合适的Buck转换器和控制器?
DC-DC电源中常用的降压稳压器,依靠两个功率开关管来执行开关功能。开关管在控制器的驱动作用下,以一定的占空比交替在电感里存储能量并释放给负载。一般从芯片是否集成了开关管来区分DCDC降压稳压器:降压转换器和降压控制器。本文将介绍如何为降压应用选择合适的Buck转换器和控制器。
