CS5157H集成电路（IC）的特殊用途稳压器规格书PDF中文资料

CS5157H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CS5157H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 CS5157H is a 5−bit synchronous dual N−Channel buck controller. It is designed to provide unprecedented transient response for today’s demanding high−density, high−speed logic. The regulator operates using a proprietary control method, which allows a 100 ns response time to load transients. The CS5157H is designed to operate over a 4.25−20 V range (VCC) using 12 V to power the IC and 5.0 V or 12 V as the main supply for conversion.
