Maxim MAX15040高效4A开关电源稳压解决方案

Maxim公司的MAX15040高效开关电源稳压器,输出电流4A,输出电压从0.6V到0.9xVIN.器件工作电压2.4V到3.6V,具有1MHz固定频率PWM模式工作,输出电压精度±1%,主要应用在服务器电源,POL,ASIC/CPU/DSP内地和I/O电源,DDR电源,基站电源以及通信和网络设备电源等.本文介绍了MAX15040主要特性,方框图, VOUT = 1.8V全陶瓷电容设计电路图以及MAX15040评估板主要特性,电路图和材料清单.

The MAX15040 high-efficiency switching regulator delivers up to 4A load current at output voltages from 0.6V to (0.9 x VIN). The device operates from 2.4V to 3.6V, making it ideal for on-board point-of-load and postregulation applications. Total output-voltage accuracy is within ±1% over load, line, and temperature.

The MAX15040 features 1MHz fixed-frequency PWM mode operation. The high operating frequency allows for small-size external components.

The low-resistance on-chip nMOS switches ensure high efficiency at heavy loads while minimizing critical parasitic inductances, making the layout a much simpler task with respect to discrete solutions. Following a simple layout and footprint ensures first-pass success in new designs.
