TPS61170-Q1
符合 AEC-Q100 标准、采用 2mm x 2mm QFN 封装的 3V 至 18V 宽输入范围 1.2A 升压转换器
【产品说明】
TPS61170-Q1 是一款集成 1.2A/40V 功率金属氧化物半导体场效应晶体管 (MOSFET) 的单片高压开关稳压器。该器件可配置为多种标准开关稳压器拓扑,包括升压和 SEPIC。该器件通过其宽输入电压范围 支持 需要由多节电池或经稳压的 5V/12V 电源轨提供输电压的应用。
TPS61170-Q1 的工作开关频率为 1.2MHz,允许使用薄型电感和低值陶瓷输入和输出电容。外部回路补偿组件支持用户灵活优化回路补偿和瞬态响应。此器件内置保护 特性,例如逐脉冲过流限制、软启动和热关断。
FB 引脚可调节为基准电压
1.229V。该基准电压可使用通过 CTRL 引脚连接的单线制数字接口(EasyScale协议)进行降低。另外,也可将一路脉宽调制 (PWM) 信号施加于 CTRL 引脚。该信号的占空比可按比例降低反馈基准电压。
TPS61170-Q1 采用 6 引脚 2mm ×
2mm SON 封装,适用于紧凑型电源解决方案。
