摘要:CS51411演示板是一个允许CS5141X 系列, A/ V降压稳压器,运行在260千赫或520千赫。通过供给时钟信号的同步输入的开关频率可以同步到一个更高的频率。并驱动SHDNB输入低关闭转换器的输出,最大限度地减少了功耗。
基本特性:
The CS5141X products are buck regulator ICs. These devices are fixed- frequency operating at 260kHz and 520kHz. The regulators use the V2 control architecture to provide unmatched transient response, the best overall regulation and the simplest pensation for today’s high- speed logic. These products modate input voltages from to 40V.
The CS51411 and CS51413 contain synchronization circuitry.

方案描述:
The CS51411 demonstration board is a A/ V buck  regulator running at 260 kHz (CS51411) or 520 kHz (CS51413). The switching frequency can be synchronized  to a higher frequency through feeding clock signals to the SYNC input. Driving SHDNB input low shuts down the  converter output and min
