SI-8050JD集成電路（IC）的穩(wěn)壓器-DC-DC開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

SI-8050JD屬于集成電路（IC）的穩(wěn)壓器-DC-DC開關(guān)穩(wěn)壓器。由三墾電氣株式會(huì)社制造生產(chǎn)的SI-8050JD穩(wěn)壓器 - DC-DC 開關(guān)穩(wěn)壓器DC-DC 開關(guān)穩(wěn)壓器 PMIC（電源管理集成電路）產(chǎn)品族中的產(chǎn)品是元器件級(jí)設(shè)備，用于需要穩(wěn)定 DC 輸入電壓和/或?qū)⑵滢D(zhuǎn)換為不同幅度的輸出電壓的應(yīng)用。這些器件與稱為“控制器”PMIC 的類似產(chǎn)品的區(qū)別在于集成了主開關(guān)元件，設(shè)備提供的電力會(huì)通過該元件。

Designed to meet high-current requirements at high efficiency in industrial and consumer applications; embedded core, memory, or logic supplies; TVs, VCRs, and office or telecommunications equipment, the SI-8050JD dc/dc step-down (buck) converter offers a constant 125 kHz switching frequency essential for low EMI noise. The npn switch is included on the die along with the oscillator, control, and logic circuitry requiring only four external components for a regulated 5.0 V output at

up to 1.5 A. .
