SL9486A：GPS 定位器的理想电源芯片
在当今的 GPS 定位器领域，稳定高效的电源供应至关重要。SL9486A 作为一款卓越的 DCDC 降压恒压芯片，以其出色的性能成为 GPS 定位器电源的专用之选。
宽输入电压，适应多样场景
SL9486A 拥有令人惊叹的 5V-100V 宽输入电压范围。无论是常见的 5V 电源，还是电动车等设备中高达 100V 的电源，它都能轻松适配。这一特性使得 GPS 定位器在各种复杂的供电环境下都能稳定工作。例如，在电动车领域，车辆电池电压在不同状态下会有所波动（如 48V、60V、72V 等），SL9486A 能完美应对，确保 GPS 定位器始终处于正常运行状态，精准追踪车辆位置。
精准降压恒压，保障定位稳定
对于 GPS 定位器而言，稳定的输出电压是精准定位的基础。SL9486A 可将输入电压稳定降压至 4.2V 或 5V，恰好满足大多数 GPS 定位器的工作电压需求。它采用先进的滞回电压模式控制技术，能够快速响应电压变化，实现高精度的电压调节，输出电压误差控制在极小范围内（<±2%）。即使在电源电压波动或定位器负载变化时，也能保证输出电压的稳定，为定位器的核心组件提供稳定可靠的电源，从而保障定位数据的准确性和实时性。
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.
