FS8S0765RCB Fairchild Power Switch (FPS™) April 2006 FS8S0765RCB Fairchild Power Switch (FPS™) Features Burst Mode Operation to Reduce the Power Consumption in the Standby Mode External pin for Synchronization and Soft Start Wide Operating Frequency Range up to 150kHz Low Start-up Current (Max:80μA) Low Operating Current (Max:15mA) Pulse by Pulse Current Limiting Over-Voltage Protection (Auto Restart Mode) Overload Protection (Auto Restart Mode) Abnormal Over-Current Protection (Auto Restart Mode) Internal Thermal Shutdown (Auto Restart Mode) Under-Voltage Lockout Internal High-Voltage SenseFET Description FS8S0765RCB is a Fairchild Power Switch (FPS) that is specially designed for off-line SMPS of CRT monitors with minimal external components. This device is a current mode pulse-width modulated (PWM) controller combined with a high-voltage power SenseFET in a single package. The PWM controller features integrated oscillator to be synchronized with the external sync signal, under-voltage lockout, optimized gate driver, temperature compensated precise current sources for the loop compensation. This device also includes various fault-protection, circuits such as over voltage protection, overload protection, abnormal over current protection and over-temperature protection, Compared with a discrete MOSFET and PWM controller solution, FPS can reduce total cost, component count, size, weight, while increasing efficiency, productivity, and system reliability. This device is well suited for the cost-effective monitor power supply. Applications SMPS for Monitor TO-220-5L 1 1. Drain 2. GND 3. VCC 4. Feedback 5.

物料型号: - 型号:FS8S0765RCB - 封装:TO-220-5L

器件简介: FS8S0765RCB是一款专为CRT显示器的离线SMPS设计的Fairchild Power Switch (FPS),集成了电流模式脉宽调制(PWM)控制器和高压功率SenseFET。该器件具有集成振荡器,可以与外部同步信号同步,并包含欠压锁定、优化的门驱动器和温度补偿的精确电流源,用于环路补偿。此外,该设备还包含过压保护、过载保护、异常过流保护和过温保护等多种保护电路。

引脚分配: 1. Drain:SenseFET漏极,高压功率SenseFET漏极连接,设计用于直接驱动变压器。 2. GND:地,控制地和SenseFET源极。 3. Vcc:供电电压,供电输入,为启动和稳态操作提供内部工作电流。 4. Feedback:反馈,内部连接到PWM比较器的反相输入,为了稳定操作,应在该引脚和GND之间放置电容器。如果该引脚的电压达到7.5V,将激活过载保护,导致FPS关闭。 5. Soft Start & Sync:软启动和同步,用于软启动和与外部同步信号的同步。

参数特性: - 工作频率范围高达150kHz - 低启动电流(最大80μA) - 低工作电流(最大15mA) - 脉冲脉冲电流限制 - 自动重启模式下的过压保护、过载保护、异常过流保护 - 自动重启模式下的内部热关机 - 欠压锁定 - 内部高电压SenseFET

功能详解: FS8S0765RCB具有多种功能,包括: 1. 启动:具有6V滞后带的UVLO电路,确保控制IC的稳定操作。 2. 反馈控制:采用主侧调节,消除了次级侧反馈电路组件。 3. 保护功能:包括AOCP、OLP、OVP和TSD等自保护功能。 4. 软启动:在初始启动期间,通过充电电容缓慢增加反馈电压,实现软启动。 5. 同步:通过外部同步信号,减少开关噪声对屏幕的影响。 6. 突发模式操作:在待机模式下最小化功耗。

应用信息: FS8S0765RCB适用于监视器SMPS。
