ADP1878-0.6-EVALZ开发板套件编程器的评估板-DC/DC与AC/DC（离线）SMPS规格书PDF中文资料

ADP1878-0.6-EVALZ属于开发板套件编程器的评估板-DC/DC与AC/DC（离线）SMPS。由亚德诺半导体技术有限公司制造生产的ADP1878-0.6-EVALZ评估板 - DC/DC 与 AC/DC（离线）SMPS该系列产品提供了一种方便的方法，可对开关模式电源转换所用的器件（包括 DC-DC 和 AC-DC 型）进行性能或特性评估。“稳压器”（包含内部电源开关装置）和“控制器”（设计为控制外部电源开关）之类的器件均包括在内。

GENERAL DESCRIPTION

The ADP1878/ADP1879 are versatile current-mode, synchronous step-down controllers. They provide superior transient response, optimal stability, and current-limit protection by using a constant on time, pseudo fixed frequency with a programmable current-limit, current control scheme. These devices offer optimum performance at low duty cycles by using a valley, current-mode control architecture allowing the ADP1878/ADP1879 to drive all N-channel power stages to regulate output voltages to as low as 0.6 V.
