NCP5425DBG概述

    Product Introduction
    The NCP5425 is a highly flexible dual buck controller with integrated gate drivers, designed to work efficiently with two input power supplies and one or two outputs. It features a feed-forward voltage mode control mechanism and is capable of driving synchronous dual NFET buck regulators. The NCP5425 supports a wide operating voltage range from 4.6V to 13.2V and can handle single two-phase or dual single-phase outputs. It is particularly suitable for applications requiring low voltage outputs with high precision and rapid transient response.
    Technical Parameters
    - Operating Voltage Range: 4.6V to 13.2V
    - Peak Power Drive: 1.5A
    - Switch Frequency: Adjustable between 150kHz to 750kHz
    - Input Undervoltage Lockout: Supports lockout at voltages below 4.2V
    - Overcurrent Protection: Features cycle-by-cycle overcurrent protection with independent programmable current limits
    - Power Supply Sequencing: Can manage power supply sequencing via the COMP pins
    - Package Type: 20-pin TSSOP
    Product Features and Advantages
    The NCP5425 offers several distinct advantages:
    - Configurability: It can operate as either a single two-phase output or two single-phase outputs.
    - Programmability: Offers programmable power sharing and budgeting from two independent supplies.
    - Noise Management: Includes switch blanking for noise-sensitive applications.
    - Compact Design: Available in a compact 20-pin TSSOP package, minimizing PCB area.
    These features make the NCP5425 ideal for applications demanding high efficiency, low noise, and precise control.
    Application Cases and Usage Recommendations
