描述 Description
The ST1S15 is a high efficiency miniaturized step-down converter able to provide 500 mA output current from an input voltage from 2.3 V to 5.5 V. This converter is specifically designed for applications where high efficiency and small application area are the key factors. Thanks to 6 MHz switching frequency, the ST1S15 can use 470 nH nominal values for the inductor and 4.7 µF for the output capacitor providing, at the same time, very good performance in terms of load and line transients. A PFM mode can be selected for high efficiency under light load conditions or PWM mode for tight regulation and best dynamic performance. Short-circuit and thermal protection are also included.
特性 Features
• 85% typical efficiency
• 500 mA output current capability
• 45 µA typical quiescent current
• PFM or PWM operation for best efficiency over whole load range
• Ultra-fast load and line transient
• Short-circuit and thermal protection
• Small external components
• Auto or forced PWM selection with dedicated pin
• Available in Flip Chip 6 package
简介
ST1S15属于集成电路(IC)的稳压器-DC-DC开关稳压器。由制造生产的ST1S15稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC(电源管理集成电路)产品族中的产品是元器件级设备,用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件,设备提供的电力会通过该元件。
