MCP1652中文资料750 KHz Step-Up DC/DC Controller w/Power Good数据手册Microchip规格书

描述 Description

The MCP1652 is a 750 kHz gated oscillator boost controller packaged in an 8 or 10-pin MSOP package. Developed for high-power, portable applications, the gated oscillator controller can deliver 5 watts of power to the load while consuming only 120 µA of quiescent current at no load. The MCP1652 can operate over a wide input voltage range (2.0V to 5.5V) to accommodate multiple primary-cell and singlecell Li-Ion battery-powered applications, in addition to 2.8V, 3.3V and 5.0V regulated input voltages.

简介

MCP1652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MCP1652DC-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。
