AP1512中文资料50KHz, 2A/3A PWM Buck DC/DC Converter数据手册Diodes规格书

描述 Description

■ General Description
The AP1512/A is a monolithic IC that design for a step-down DC/DC converter, and own the ability of driving a 2A (3A for AP1512A) load without additional transistor component. Due to reducing the number of external component, the board space can be saved easily. The external shutdown function can be controlled by logic level and then come into standby mode. The internal compensation makes feedback control have good line and load regulation without external design.■

简介

AP1512属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的AP1512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。
