NCP81142規(guī)格書詳情
NCP81142屬于集成電路（IC）的特殊用途穩(wěn)壓器。由安森美半導(dǎo)體公司制造生產(chǎn)的NCP81142特殊用途穩(wěn)壓器該系列產(chǎn)品用于電源控制、某種形式的轉(zhuǎn)換，適用于特定的復(fù)雜應(yīng)用。因此，各種產(chǎn)品特性集差異較大，包括空燃比傳感器接口、汽車交流發(fā)電機(jī)電壓調(diào)節(jié)、DDR 端接、液體透鏡控制、摩托車轉(zhuǎn)向信號控制、熱電 (peltier) 冷卻器控制、壓電觸覺控制、閥門控制、小型發(fā)動機(jī)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.
