在电子设备的电源管理中，一款性能强劲、适配性高的芯片至关重要。当面临高电压环境以及对稳压、电流输出有严格要求时，你是否在寻找更优解决方案？现在，100V 耐压芯片 SL9486A 为你带来全新选择，它能稳压输出可调，提供 2A 持续电流，是替代 LM2576HV 的理想之选。

SL9486A 拥有高达 100V 的耐压能力，相比 LM2576HV，在应对更高电压的应用场景时更加从容。无论是工业控制、安防监控还是其他需要高电压输入的设备，SL9486A 都能稳定运行，保障设备正常工作，减少因电压波动导致的故障风险。

稳压输出可调是 SL9486A 的又一显著优势。它可以根据不同设备的需求，灵活调整输出电压，满足多样化的用电需求。而 LM2576HV 在电压调节的灵活性上稍显逊色。SL9486A 的这一特性，使得它在不同的电路设计中都能轻松适配，为工程师们提供了更大的设计空间。

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.
