SC4530集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

SC4530属于集成电路（IC）的稳压器-DC-DC开关稳压器。由Semtech Corporation制造生产的SC4530稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。

Description

The SC453 IC is a single chip high-performance Hysteretic PWM controller. With its integrated SmartDriver™, it pow ers advanced graphics and core processors. It provides sleep mode and boot voltage support. Automatic power save is present to prevent negative current flow in the

low-side FET during light loading conditions saving even more power. The high side driver initially turns on with a weak drive to reduce ringing, EMI, and capacitive turn-on of the low side.
