Intersil ZL9101M数字12A DC电源解决方案

Intersil公司的 ZL9101M是数字DC/DC PMBus 12A 电源模块，模块中包括有高性能的数字PWM控制器，功率MOSFET，电感和所有的无源元件，形成了完整的DC/DC电源解决方案。输入电压很宽，输出电压0.6-4V，可通过PMBus采用外设电阻设定。模块主要用在服务器，通信和数据通信，工业和医疗设备以及通用的点负载。本文介绍了ZL9101M 主要特性，12A 应用电路以及.

The ZL9101M is a 12A variable output step-down PMBus-compliant digital power supply. Included in the module is a high performance digital PWM controller, power MOSFETs, an inductor, and all the passive components required for a complete DC/DC power solution. The ZL9101M operates over a wide input voltage range and supports an output voltage range of 0.6V to 4V, which can be set by external resistors or via PMBus. This high efficiency power module is capable of delivering 12A. Only bulk input and output capacitors are needed to finish the design. The output voltage can be precisely regulated to as low as 0.6V with ±1% output voltage regulation over line, load, and temperature variations.

The ZL9101M features internal compensation, internal soft-start, auto-recovery overcurrent protection, an enable option, and pre-biased output start-up capabilities.
