产品概述

描述

ST1PS03是一款Nano-Quiescent同步整流降压转换器,能够提供高达400mA的输出电流,输入电压范围为1.8V至5.5V。该产品专为高效率及对PCB尺寸和对厚度有要求的应用而设计。

可以使用三个数字控制输入设置输出电压,也可以动态选择1.6 V至3.3 V的VOUT 。由于增强的PCC(峰值电流控制),ST1PS03仅使用2.2μH电感和两个小电容即可实现极高的效率转换。开发先进的设计电路以最小化静态电流。该器件嵌入了一个可从VIN_AUX访问的受控开关,以便为子系统供电。最后,它采用薄塑料封装。

  • 所有功能

    • VIN=3.6 V(没有开关)时500 nA输入静态电流
    • 10 mA负载(VIN=3.6 V, VOUT=2.5 V)时典型效率为92%
    • 100%占空比
    • 输入电压范围为1.8 V至5.5 V
    •  欠压锁定:1.57 V (VIN falling, typ.)
    • 输出电流能力高达400 mA
    • 低功率控制操作,以实现最佳效率
    • 嵌入式软启动电路
    • 微小的外部元件:L = 2.2 µH typ.
    • 可选输出电压:1.6 V至3.3 V
    • 输出电压供电正常
    • ±1.5%输出电压精度(VOUT, TA = 25 °C)
    • 动态输出电压选择(D0、D1和D2)
    • 由AUX输入控制的负载开关
    • 采用TQFN12封装
