MC34712EP概述

    Product Overview: MC34712 SmartMOS 34712 Buck Switching Regulator
    The MC34712, manufactured by NXP Semiconductors, is a highly integrated and cost-effective single synchronous buck switching regulator with integrated N-channel power MOSFETs. Designed to deliver precise and reliable power solutions, the MC34712 excels in point-of-load (PoL) applications, especially within the realm of modern data bus systems such as DDR memory.
    Product Introduction
    Basic Features
    The MC34712 is an advanced buck converter that combines high integration and efficiency to provide robust power management capabilities. Its primary function is to generate a termination voltage (VTT) and buffered reference voltage (VREF) required by DDR memory systems. This product supports DDR, DDR2, DDR3, and DDR4 memory architectures, making it a key component in server-grade electronics, desktop motherboards, gaming consoles, and telecommunication equipment.
    Applications
    - DDR memory termination (VTT and VREF)
    - Power supply for active buses and graphics card memory
    - Servers and telecom applications
    - Desktop motherboards and high-definition TVs
