TPS54061-Q1器件是一款60V,200mA,同步降压dc-dc转换器,此转换器具有高侧和低侧MOSFET。电流模式控制提供简单的外部补偿和灵活的组件选择。非开关电源电流为90μA。使能引脚的使用将关断电流减少至1.4μA。
为了增加轻负载效率,当电感器电流达到零值时,低侧MOSFET仿真一个二极管。
内部欠压闭锁设置值为4.5V,但是在使能引脚上使用2个电阻器能够增加此设置值。缓启动时间控制输出电压启动斜升。
可调开关频率范围可实现效率和外部组件尺寸的优化。频率折返和热关断功能负责在过载情况下保护器件。
TPS54061-Q1通过集成MOSFET,引导再充电二极管,以及将集成电路(IC)封装尺寸大大减小为小型3mm x 3mm散热增强型超薄小外形尺寸无引线(VSON)封装来实现小型设计。
