TEA1723BT/N1,118概述

    # TEA1723BT HV Start-up Flyback Controller Technical Overview
    1. Product Introduction
    The TEA1723BT is a compact, low-cost Switched Mode Power Supply (SMPS) controller IC designed specifically for power applications up to 11 W. It operates directly from the rectified universal mains input, making it ideal for both domestic and industrial use cases. Key advantages include an integrated high-voltage power switch (700 V), efficient performance across the entire load range, and ultra-low power consumption during no-load conditions. The TEA1723BT simplifies design by eliminating the need for an additional secondary feedback circuitry using primary-side sensing.
    Applications
    The TEA1723BT is widely used in:
    - Battery chargers for mobile phones, tablets, and similar devices.
    - Standby power supplies for TVs, desktop PCs, and set-top boxes.
    - Power supply systems for white goods like washing machines and refrigerators.
    2. Technical Parameters
    The following are the key technical specifications of the TEA1723BT:
    | Parameter | Range | Unit |
    |
    | Power Switch (Pin: DRAIN) | On-state Resistance (RDSon) | 3.5–6 Ω |
    Drain-Source Breakdown Voltage (V(BR)DS) | 700 V |
    | Oscillator (Pins: DRAIN and SOURCE) | Burst Frequency (fburst) | 815–995 Hz |
    Maximum Oscillator Frequency (fosc-high) | 48–53 kHz |
    | Supply (Pin: VCC) | Start-up Supply Voltage (VCC(startup)) | 15–19 V |
    Stop Supply Voltage (VCC(stop)) | 7.5–9.5 V |
    | Feedback (Pin: FB) | Feedback Reference Voltage (Vref(fbck)) | 2.5–2.6 V |
    | Thermal Characteristics | Junction-to-Ambient Thermal Resistance (Rth(j-a)) | 136 K/W |
    | Current Characteristics | Supply Current (ICC) during Energy Save | 90–170 µA |
    The TEA1723BT offers efficient switching with burst mode functionality, ensuring very low power consumption even in standby or no-load conditions.
    3. Product Features and Advantages
    The TEA1723BT offers several distinct advantages that make it a top choice in its application domain:
    - Energy Efficiency: High-efficiency switching over the entire load range and ultra-low power consumption (< 25 mW) during no-load conditions.
    - Integrated Components: Combines a high-voltage power switch with minimal external components, reducing cost and complexity.
    - Green Features: Compliant with Energy Star 2.0 standards and supports an energy saver mode for reduced power consumption.
    - Protection Mechanisms: Built-in protections include OverVoltage Protection (OVP), UnderVoltage LockOut (UVLO), and OverTemperature Protection (OTP).
    - Noise Reduction: Equipped with a jitter function to minimize electromagnetic interference (EMI).
    4. Application Case Studies and Usage Recommendations
    The TEA1723BT is particularly suited for battery chargers, standby supplies, and white goods applications where efficiency and space optimization are critical.
    Example Use Case:
    For a battery charger application, the TEA1723BT can efficiently regulate voltage and current with minimal external components. To maximize performance:
    - Ensure proper isolation and grounding to prevent interference.
    - Optimize PCB layout for heat dissipation and electromagnetic compatibility (EMC).
    - Implement feedback loop compensation to enhance stability and transient response.
    Practical Tip:
    When designing a circuit around the TEA1723BT, always refer to the recommended component values provided in the datasheet to ensure optimal performance.
    5. Compatibility and Support
    The TEA1723BT is compatible with standard PCB layouts and can interface seamlessly with existing systems. NXP Semiconductors provides comprehensive support, including detailed documentation, application notes, and software tools to assist engineers in implementing the chip e
