SIP11205屬于集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器。由威世科技半導體制造生產(chǎn)的SIP11205DC-DC 開關(guān)控制器PMIC（電源管理集成電路）DC 到 DC 開關(guān)式控制器是用于高效率電路的穩(wěn)壓 IC，其配置為生成高于（突升或步升）或低于（突降或步降）輸入電源的輸出電源電壓。其他拓撲結(jié)構(gòu)可能包括：降壓-升壓、反激、正激、Cuk、SEPIC、全橋、半橋和推挽式。這些器件不同于需要最小電壓并“燒盡”多余電壓的線性穩(wěn)壓器。

DESCRIPTION

SiP11205 is a feed-forward controller for the primary side of a half-bridge intermediate bus converter (IBC). It is ideally suited for isolated applications such as telecom, data communications and other products requiring an IBC architecture and conversion of standard bus voltages such as 48 V to a lower intermediate voltage, where high efficiency is required at low output voltages (24 V, 12 V, 9 V or 5 V).

Designed to operate within the telecom voltage range of 36 V to 75 V and withstand 100 V transients for a period of 100 ms, the IC is designed for controlling and driving both the low- and high-side switching devices of a half-bridge converter.
