NCP81143规格书详情

NCP81143属于集成电路(IC)的特殊用途稳压器。由安森美半导体公司制造生产的NCP81143特殊用途稳压器该系列产品用于电源控制、某种形式的转换,适用于特定的复杂应用。因此,各种产品特性集差异较大,包括空燃比传感器接口、汽车交流发电机电压调节、DDR 端接、液体透镜控制、摩托车转向信号控制、热电 (peltier) 冷却器控制、压电触觉控制、阀门控制、小型发动机管理等。

The NCP81142 Multi−Phase buck solution is optimized for

Intel® VR12.5 compatible CPUs with user configurations of 4/3/2/1

phases. The controller combines true differential voltage sensing,

differential inductor DCR current sensing, input voltage

feed−forward, and adaptive voltage positioning to provide accurately

regulated power for both Desktop and Notebook applications. The

control system is based on Dual−Edge pulse−width modulation

(PWM) combined with DCR current sensing providing the fastest

initial response to dynamic load events at reduced system cost. It has

the capability to shed to single phase during light load operation and

can auto frequency scale in light load conditions while maintaining

excellent transient performance.

High performance operational error amplifiers are provided to

simplify compensation of the system. Patented Dynamic Reference

Injection further simplifies loop compensation by eliminating the need

to compromise between closed−loop transient response and Dynamic

VID performance. Patented Total Current Summing provides highly

accurate digital current monitoring.
