Intersil ZL2008 3A数字电源解决方案

Intersil 公司的ZL2008是数字DC/DC电源控制器,集成了3A MOSFET驱动器,均流特性允许多个器件并联连接给负载供电,以满足更高电流的需求.输入电压3V-14V,输出电压0.64V-5.5V,输出电压精度±1%,并具有快速负载瞬态响应,集成了和PMBus兼容的I2C/SMBus接口,主要用在服务器/存储器设备,通信/数据通信设备以及电源模块.本文介绍了ZL2008主要特性,方框图, 12V输入输出1.8V/16A应用电路图, 三相均流方框图以及ZL2008EVAL1Z评估板主要特性,电路图,PCB布局图和材料清单.

The ZL2008 is a digital DC/DC controller with integrated MOSFET drivers. Current sharing allows multiple devices to be connected in parallel to source loads with very high current demands. Adaptive performance optimization algorithms improve power conversion efficiency. Zilker Labs Digital-DC™ technology enables a blend of power
conversion performance and power management features.

The ZL2008 is designed to be a flexible building block for DC power and can be easily adapted to designs ranging from a single-phase power supply operating from a 3.3V input to a multi-phase supply operating from a 12V input. The ZL2008 eliminates the need for complicated power supply managers as well as numerous external discrete components.
