LM20133是一个全功能的同步降压稳压器能够提供高达3A的连续输出电流。 The current-mode control loop can be compensated and stabilized with almost any type of output capacitor. In most cases, compensation devices, which require only two external components, provide maximum flexibility and ease of use. Optimized operation from 2.95V to 5.5V input voltage range, making it suitable for a wide range of devices in low voltage systems.
The device features internal overvoltage protection (OVP) and overcurrent protection (OCP) circuitry to improve system reliability. A high-precision enable pin and integrated undervoltage lockout allow for tight control and sequencing of the device. Both a fixed internally and externally adjustable soft-start circuit start-up inrush current is limited. Possible with integrated power good circuit fault detection and power sequencing.
LM20133的开关频率可同步至一个外部时钟使用SYNC引脚。 SYNC引脚同步输入信号范围从500 kHz至1.5 MHz。
LM20133是在多轨电源架构设计工作。 The output voltage of the device can be configured to track a higher voltage rail, using SS/TRK pins. 如果LM20133的输出预偏置启动时，它不会吸收电流拉输出低，直到内部软启动斜坡超过电压反馈引脚。
LM20133是在一个16引脚的eTSSOP封装提供带裸焊盘的可焊接到PCB上，省去了笨重的散热器需要。
