LTC1983ES6-5#TR概述

    # Introduction to the LTC1983-3/LTC1983-5 Negative Charge Pump Converters
    The LTC1983-3 and LTC1983-5 are innovative inverting charge pump DC/DC converters designed to generate regulated negative outputs, making them ideal for portable electronic systems requiring negative voltage supplies. These compact converters feature minimal external components—only three tiny capacitors—and can deliver up to 100mA of output current. They are capable of operating in either open-loop mode (producing a –VIN supply) or regulated output mode, depending on the input voltage and output current requirements.
    These devices are tailored for portable equipment, LCD bias supplies, and GaAs FET bias supplies, among other applications. Their standout features include low quiescent current (25µA typical), a zero current shutdown mode programmable through the SHDN pin, and protection against over-temperature and short circuits. Encased in a 6-pin low-profile ThinSOT package, they offer high integration and reliability.
    Technical Parameters
    Below are the key technical specifications of the LTC1983-3/LTC1983-5:
    | Parameter | Value |

    | Input Voltage Range | 2.3V to 5.5V |
    | Output Voltage | -3V (LTC1983-3) / -5V (LTC1983-5) |
    | Output Current | Up to 100mA |
    | Quiescent Current | 25µA typical |
    | Shutdown Current | ≤1µA |
    | Switching Frequency | Internal 900kHz |
    | Output Voltage Accuracy | ±4% |
    | Operating Temperature Range| -40°C to 85°C |
    | Package | 6-pin ThinSOT (1mm height) |
    Key performance highlights include:
    - Low ESR ceramic or tantalum capacitors recommended for optimal performance.
    - High efficiency with an internal oscillator running at 900kHz.
    - Short-circuit and thermal protection ensuring robustness.
    Product Features and Advantages
    The LTC1983-3/LTC1983-5 offer several distinct advantages that make them a standout choice in the market:
    - Compact Design: Minimal footprint with only three external capacitors simplifies PCB layout.
    - Low Power Consumption: Ultra-low quiescent current (25µA typical) and a shutdown mode consume negligible power, making them suitable for battery-powered devices.
    - Robust Protection: Short-circuit and over-temperature protection ensure long-term reliability.
    - Wide Operating Range: Operates across a wide input voltage range (2.3V to 5.5V).
    - Industry-Standard Packaging: The ThinSOT package offers excellent thermal performance and space savings.
    These features make the LTC1983-3/LTC1983-5 particularly appealing for applications such as LCD biasing, GaAs FET drivers, and portable electronics where space and efficiency are critical.
    Application Case Studies and Usage Tips
    Typical Applications:
    1. LCD Bias Supplies: Generate -3V or -5V for driving LCD panels.
    2. GaAs FET Bias Supplies: Provide stable negative voltages for RF power amplifiers.
    3. General Inverting DC/DC Conversion: Converts single-supply positive voltages into regulated negative outputs.
    Usage Recommendations:
    - Always place a bypass capacitor (≥4.7µF) close to the VIN and VOUT pins to minimize noise and ripple.
    - Use a ceramic capacitor (0.1µF to 4.7µF) for the flying capacitor to achieve better switching efficiency.
    - For applications requiring lower output ripple, opt for a larger COUT capacitor (10µF to 22µF).
    - Ensure proper grounding and avoid floating the SHDN pin to prevent unintended behavior.
    For instance, in an LCD bias supply, placing a 10µF tantalum capacitor in parallel with a 1µF ceramic capacitor can significantly reduce output ripple while maintaining sufficient current handling capability.
