SANKEN ELECTRIC DC-DC稳压器 NR263S

NR263S概述

    Product Overview: NR263S Synchronous Rectification Buck Converter
    The NR263S is a highly efficient synchronous rectification buck converter integrated circuit (IC) designed by Sanken Electric Co., Ltd. It features built-in power MOSFETs and is optimized for light-load efficiency, making it ideal for applications where low power consumption and compact size are critical. This product is widely used in consumer electronics, white goods, audiovisual equipment, and other applications requiring regulated DC-DC conversion.
    Key Features:
    - Synchronous Rectification: Enhances efficiency by reducing losses during the rectification process.
    - Adaptive Operation Modes:
    - Normal Load: Current Mode PWM Control.
    - Light Load: Pulse Skip Mode for improved efficiency.
    - Maximum Efficiency:
    - Normal Load (1A): 94%
    - Light Load (10mA): 86%
    - Stable with Low ESR Capacitors: Supports ceramic capacitors, reducing overall system cost and complexity.
    - Few External Components: Simplifies design and reduces BOM costs.
    - Soft-Start Functionality: Adjustable startup time for smoother power transitions.
    - Integrated Protection Mechanisms:
    - Overcurrent Protection (OCP)
    - Undervoltage Lockout (UVLO)
    - Thermal Shutdown (TSD)
