基于UCC24610 型号的二次侧同步整流器控制器
描述 This GREEN Rectifier controller is a high-performance controller and driver for standard and logic-level N-channel MOSFET power devices used for low-voltage secondary-side synchronous rectification. The combination of controller and MOSFET emulates a near-ideal diode rectifier. This solution not only directly reduces power dissipation of the rectifier but also indirectly reduces primary-side losses as well, due to compounding of efficiency gains. Using drain-to-source voltage sensing, the UCC24610 is ideal for Flyback and LLC-resonant power supplies but can also be used with other power architectures. The UCC24610 is optimized for output voltages from 4.5 V to 5.5 V, and is suitable for use with lower and higher output voltages as well. The UCC24610 offers a programmable false-triggering filter, a programmable timer to automatically switch to light-load mode at light load, and a SYNC input for optional use in continuous conduction mode (CCM) systems. Protection features on TON and EN/TOFF pins prevent run-away on-time due to open-circuit or short-circuit fault conditions. This device is available in an 8-pin SOIC package and an 8-pin, 3.0-mm × 3.0-mm SON package with an exposed thermal pad. 特性 Secondary-Side Controller Optimized for 5-V Systems Up to 600-kHz Operating Frequency VDS MOSFET-Sensing 1.6-Ω Sink, 2.0-Ω Source Gate-Drive Impedances Micro-Power Sleep Current for 90+ Designs Automatic Light-Load Management Synchronous Wake-Up From Sleep and Light-Load Modes Protection Features on Programming Inputs SYNC Input for CCM Operation 20-ns Typical Turnoff Propagation Delay Improved Efficiency and Design Flexibility Over Traditional Diode Solution May Be Biased Directly From 5-V Output Minimal Component Count APPLICATIONS AC-to-DC 5-V Adapters 5-V Bias Supplies Low Voltage Rectification Circuits Flyback and LLC Converters 相关终端应用 Circuit Breaker Data Encoders/Decoders Distribution Amplifiers Drone Accessories EV 基础设施 - 1&2 级 EVSE Electronic Warfare HDTV LCD 测试设备 LED 驱动器 Relay AC Analog Input Module Relay Power Supply Module Up/Down/Cross Conversion 一体式打印机 三相 UPS 交流/直流功率计和分析器 交流电源、直流电源和电子负载 产妇和新生儿护理监视器 仪表(实验室、分析、现场) 保护继电器 - 特殊功能 内存和半导体测试设备 出口和紧急照明 功率传输单元 医疗 PSU 单相 UPS 变电站自动化 - IEC61850 过程总线 台式计算机/主板 商用 DIN 导轨电源 商用电池充电器 商用网络和服务器 PSU 工业 AC-DC 平板电脑：多媒体 无线通信测试设备 普通笔记本电脑 智能手机 标准打印机 电器电池充电器 电子病床和床控制器 电池测试设备 电视电源 直流充电(桩)站 示波器 (DSO) 移动壁式充电器设计 超高清 4K OLED 电视 超高清 LCD 电视 远程保健系统 适用于广播的布线和传输系统 配电自动化 - 终端设备 Iczoom拍明芯城聚焦于中小企业需求，具有货源可靠、品类齐全、交付及时、价格实惠、方案众多的特点和服务优势，客户来源非常丰富，原厂、代理商、正品经销商、同行电商、终端商均有注册。 Iczoom拍明芯城严格把控卖家资质和货品质量，快速匹配买卖信息，帮助客户“卖得快、买得全”。同时，Iczoom拍明芯城为中小企业提供专业的管理软件和全程供应链服务，让客户轻松实现内部的数据化管理。
