产品概述
描述
ST1PS02是一款极低静态电流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引脚设置输出电压，也可以动态选择1.0 V至3.3 V的VOUT 。由于增强的PCC（峰值电流控制），ST1PS02仅使用2.2μH电感和两个小电容即可实现极高的效率转换。该器件内嵌一个受控负载开关，为子系统提供相同电压轨。实现先进的设计电路以最小化静态电流该器件采用薄塑料封装。-
所有功能
- VIN=3.6 V（没有开关）时的输入静态电流为500 nA
- 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 (典型值)
- 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 = 2.2 µH typ.
- 可设置电感电流限制
- 可选输出电压：1.0 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）
- 辅助负载开关Vout2（AUX控制输入）
- 采用TQFN12封装
