MONOLITHIC POWER SYSTEMS DC-DC稳压器 MP2102DQ-LF-Z

MP2102DQ-LF-Z概述

    MP2102: 1.5MHz, 800mA Dual-Output Synchronous Step-Down Converter
    1. Product Introduction
    The MP2102 is a highly efficient dual-output synchronous step-down converter designed to power portable devices from a single-cell Lithium-Ion (Li+) battery. This converter operates at a fixed frequency of 1.5MHz and supports a dual output voltage configuration, making it ideal for portable electronics such as smartphones, digital cameras, and personal digital assistants (PDAs). Each channel of the MP2102 can supply up to 800mA of load current, with an input voltage range of 2.5V to 6V and output voltages adjustable down to 0.6V.
    Key applications include DVD players, smartphones, PDAs, digital cameras, and portable instruments. The MP2102 integrates high-side switches and synchronous rectifiers, which allow for high-efficiency step-down conversion without requiring external Schottky diodes. Its advanced internal compensation and stable operation with ceramic capacitors make it a reliable choice for space-constrained designs.
    2. Technical Parameters

    | Input Undervoltage Lockout | Yes
    3. Product Features and Advantages
    The MP2102 offers several advantages that set it apart from competitors:
    - Dual Outputs: Two independent channels each delivering up to 800mA.
    - High Efficiency: Operates at up to 95% efficiency, minimizing power loss.
    - Internal Compensation: Simplifies design by eliminating the need for external components.
    - Small Footprint: Available in compact 10-pin QFN (3mm x 3mm) and MSOP10 packages.
    - Cycle-by-Cycle Current Limiting: Protects the internal switch from overloads.
    - Programmable Power-On Reset: Ensures system stability with precise timing control.
    Its ability to work with ceramic capacitors makes it especially suitable for modern electronics where small form factors are essential.
    4. Application Case Studies and Usage Recommendations
    The MP2102 excels in various applications, including:
    1. Smartphones: Efficient power delivery to multiple circuits like display drivers and audio subsystems.
    - Recommendation: Use an inductor with a 2.2µH inductance and a ceramic output capacitor to ensure optimal performance.
    2. Portable Instruments: Compact and reliable power supply solutions for medical devices and IoT applications.
    - Recommendation: Optimize thermal management by using larger heat sinks if both channels are operating under full load.
    3. Digital Cameras: Provides stable and efficient power for sensor arrays and flash units.
    - Recommendation: Select an input capacitor with low ESR to reduce ripple and maintain steady performance.
    5. Compatibility and Support
    The MP2102 is compatible with a wide range of electronic systems due to its standard pin configuration. Monolithic Power Systems (MPS) provides comprehensive documentation, evaluation boards (EV2102DQ-00B), and customer support to aid in integration. The company also offers RoHS-compliant packag
