AP2014中文资料buck-controller数据手册Diodes规格书

描述 Description

The AP2014 controller IC is designed to provide a low cost synchronous Buck regulator for on-board DC to DC converter applications. With today’s ASIC products requiring supply voltages at 1.8V and lower, when the output current is as much as 3A and the input voltage is at either 3.3V or 5V, traditional linear regulator simply incurs too much loss within itself. The AP2014 together with dual N-channel MOSFETs provide a low cost solution for such applications. This device features an internal 200KHz oscillator (400KHz for \"A\" version), under-voltage lockout for both Vcc and Vc supplies, an external programmable soft-start function as well as output under-voltage detection that latches off the device when an output short is detected.

简介

AP2014属于集成电路（IC）的PMIC-稳压器-DCDC开关式控制器。由Diodes制造生产的AP2014DC-DC 开关控制器PMIC（电源管理集成电路）DC 到 DC 开关式控制器是用于高效率电路的稳压 IC，其配置为生成高于（突升或步升）或低于（突降或步降）输入电源的输出电源电压。其他拓扑结构可能包括：降压-升压、反激、正激、Cuk、SEPIC、全桥、半桥和推挽式。这些器件不同于需要最小电压并“烧尽”多余电压的线性稳压器。
