LTC1261CS8-4.5#PBF概述

    LTC1261 Switched-Capacitor Voltage Inverter: Comprehensive Technical Overview
    Product Introduction
    The LTC1261 is a highly efficient, compact switched-capacitor voltage inverter developed by Linear Technology (now part of Analog Devices). Designed to generate a regulated negative voltage from a single positive supply, the LTC1261 finds applications across various industries, including battery-powered systems, single-supply circuits, GaAs FET bias generators, and negative supply generators. Its primary function is to produce a regulated negative voltage, making it particularly useful in scenarios where dual supply rails are needed.
    Technical Parameters
    The LTC1261 operates within a supply voltage range of 3V to 8V, offering an adjustable output voltage range of -1.25V to -8V. Below are key technical specifications:
    - Output Current: Up to 12mA with guaranteed output regulation of 5%.
    - Voltage Ripple: Typically as low as 5mV.
    - Quiescent Current: 600µA when active; reduced to 5µA in shutdown mode.
    - Package Options: Available in 8-pin SO and 14-pin narrow body SO packages.
    - Input Capacitors: One or two external 0.1µF capacitors required, depending on input voltage.
    - Temperature Range: Commercial grade (0°C to 70°C); Industrial grade (-40°C to 85°C).
    Product Features and Advantages
    The LTC1261 stands out due to its:
    - Wide Operating Voltage Range: Adapts to varying power sources.
    - Low Output Ripple: Ensures high-quality negative voltage generation.
    - Adjustable/Fixed Output Options: Provides flexibility in design.
    - Compact Footprint: Reduces space requirements in printed circuit boards.
    - Efficient Power Consumption: Minimizes quiescent current during operation.
    - Enhanced Reliability: Robust design ensures longevity even under challenging conditions.
    These features make the LTC1261 a superior choice for portable and embedded electronics requiring precise negative voltage generation.
    Application Case Studies and Usage Recommendations
    The LTC1261 is ideal for applications such as:
    - Generating a regulated -5V supply from a 3V source.
    - Serving as a regulator with a Power Valid Indicator (REG Pin).
    - Supporting low output ripple environments.
    Usage Suggestions:
    - Use external capacitors judiciously to optimize performance and minimize output ripple.
    - Ensure proper grounding and bypassing to maximize efficiency.
    - Consider the internal resistor string (R0, R1, RADJ) to fine-tune output voltage settings.
    Compatibility and Support
    The LTC1261 integrates seamlessly with other electronic components due to its compatibility with standard power supplies. Linear Technology offers comprehensive support, including detailed datasheets, application notes, and software tools for easy integration into designs.
    Common Issues and Solutions
    Below are common issues users might face and practical solutions:
    | Issue | Solution |

    | High output ripple | Increase output capacitance (≥3.3µF). |
    | Excessive quiescent current | Check external circuit connections and correct any shorts. |
    | Insufficient output current | Ensure proper capacitor values and connections per data sheet. |
    Conclusion and Recommendation
    The LTC1261 excels in delivering reliable, stable negative voltage outputs, making it a premier choice for a wide range of electronic applications. Its robust design, minimal footprint, and ease of integration make it highly suitable for modern electronic systems. We strongly recommend the LTC1261 for projects requiring efficient negative voltage generation, especially in battery-powered devices and single-supply environments.
