NCV6357MTWATXG集成电路（IC）的特殊用途稳压器规格书PDF中文资料

NCV6357MTWATXG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NCV6357MTWATXG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 NCV6357 is a synchronous AOT (Adaptive On−time) buck

converter optimized to supply the different sub systems of automotive

applications post regulation system up to 5 V input. The device is able

to deliver up to 5.0 A, with programmable output voltage from 0.6 V

to 3.3 V. Operation at up to 2.4 MHz switching frequency allows the

use of small components. Synchronous rectification and automatic

PFM Pseudo−PWM (PPWM) transitions improve overall solution

efficiency. The NCV6357 is in low profile 3.0 × 4.0 mm DFN−14 package.
