MP2493DS-LF-Z概述

    MP2493 2A, 36V Low EMI Step-Down Converter: A Comprehensive Overview
    Product Introduction
    The MP2493 is a highly efficient monolithic step-down switch mode converter manufactured by Monolithic Power Systems (MPS). It supports an output current of up to 2A with programmable current limiting capabilities, making it ideal for various power management applications. Key features include a wide operating input voltage range (4.5V to 36V), programmable output voltage ranging from 0.8V to 15V, and excellent load and line regulation performance.
    This product finds its primary applications in USB power supplies, automotive cigarette lighter adapters, and linear charger power supplies. The compact footprint and advanced design make it particularly suited for space-constrained environments.
    Technical Parameters
    The MP2493 offers impressive technical specifications:
    - Input Voltage Range: 4.5V to 36V
    - Output Voltage Range: 0.8V to 15V
    - Continuous Output Current: Up to 2A
    - Switching Frequency: Fixed at 130kHz (with options for frequencies up to 160kHz)
    - Efficiency: Up to 95%
    - Protection Features: Cycle-by-cycle current limiting, thermal shutdown, and UVLO (under-voltage lockout) with hysteresis
    - Packages: Available in 8-pin SOIC and 8-pin SOIC8E configurations
    - Operating Temperature Range: –40°C to +125°C
    Product Features and Advantages
    The MP2493 stands out with several key advantages:
