LV5052V中文资料LV5052V: Buck Converter Controller, DC-DC, 2-Channel数据手册ONSEMI规格书

描述 Description

LV5052V is a high efficiency, 2-channel, step-down DC-DC converter controller IC, adopting a synchronous rectification system. Incorporating numerous functions on a single chip with easy external setting, it can be used for a wide variety of applications. The device is optimal for use in multi-output power supply systems which are used in LCD-TVs, DVD recorders, game machines, high-end office products, etc.

特性 Features

Integrated UVLO circuit, overcurrent detection, soft-start/soft-stop, and start-up delay functions
Integrated output voltage monitoring function (POWERGOOD and timer latch)

简介

LV5052V属于集成电路（IC）的PMIC-稳压器-DCDC开关式控制器。由制造生产的LV5052VDC-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。
