L296PHT集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

L296PHT属于集成电路（IC）的稳压器-DC-DC开关稳压器。由意法半导体集团制造生产的L296PHT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 L296andL296P are stepdownpower switching regulators delivering 4 A at a voltage variable from 5.1 V to 40 V.
