ST1PS01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。 可以使用两个数字控制输入设置输出电压，也可以动态选择1.8 V至3.3 V的VOUT 。由于增强的PCC（峰值电流控制），ST1PS01仅使用2.2μH电感和两个小电容即可实现极高的效率转换。 实现先进的设计电路以最小化静态电流该器件采用Flip-Chip芯片封装。
主要特性
- VIN=3.6 V时500 nA输入静态电流（没有开关频率）
- 1mA负载时典型效率为94％(VIN=3.6 V, VOUT=3.3 V)
- 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 A
- 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 =2.2μH typ.
- 可选输出电压：1.8 V至3.3 V
- 输出电压电源良好
- ±1.5％输出电压精度(VOUT, TA=25 °C)
- 动态电压选择（D0，D1）
- 采用Flip-Chip芯片封装
