SL9486A：GPS 定位器的理想電源芯片
在當今的 GPS 定位器領(lǐng)域，穩定高效的電源供應至關(guān)重要。SL9486A 作為一款卓越的 DCDC 降壓恒壓芯片，以其出色的性能成為 GPS 定位器電源的專(zhuān)用之選。

寬輸入電壓，適應多樣場(chǎng)景
SL9486A 擁有令人驚嘆的 5V-100V 寬輸入電壓范圍。無(wú)論是常見(jiàn)的 5V 電源，還是電動(dòng)車(chē)等設備中高達 100V 的電源，它都能輕松適配。這一特性使得 GPS 定位器在各種復雜的供電環(huán)境下都能穩定工作。例如，在電動(dòng)車(chē)領(lǐng)域，車(chē)輛電池電壓在不同狀態(tài)下會(huì )有所波動(dòng)（如 48V、60V、72V 等），SL9486A 能完美應對，確保 GPS 定位器始終處于正常運行狀態(tài)，精準追蹤車(chē)輛位置。

精準降壓恒壓，保障定位穩定
對于 GPS 定位器而言，穩定的輸出電壓是精準定位的基礎。SL9486A 可將輸入電壓穩定降壓至 4.2V 或 5V，恰好滿(mǎn)足大多數 GPS 定位器的工作電壓需求。它采用先進(jìn)的滯回電壓模式控制技術(shù)，能夠快速響應電壓變化，實(shí)現高精度的電壓調節，輸出電壓誤差控制在極小范圍內（<±2%）。即使在電源電壓波動(dòng)或定位器負載變化時(shí)，也能保證輸出電壓的穩定，為定位器的核心組件提供穩定可靠的電源，從而保障定位數據的準確性和實(shí)時(shí)性。


DESCRIPTION
The SL9486A is a high-voltage, step-down, switching regulator that delivers up to 2A of continuous current to the load. It integrates a high-side, high-voltage, power MOSFET with a current limit of 3.5A, typically. The wide 5V to 100V input range accommodates a variety of step-down applications, making it ideal for automotive, industry, and lighting applications. Hysteretic voltage-mode control is employed for very fast response. The switching frequency can be up to 1MHz, allowing for small component size. Thermal shutdown and short-circuit protection (SCP) provide reliable and fault-tolerant operations. A 200μA quiescent current allows the SL9486A to be used in battery-powered applications. The SL9486A is available in ESOP8 package.
