基于UCC28600型号的准谐振反向控制器
描述 The UCC28600 is a PWM controller with advanced energy features to meet stringent world-wide energy efficiency requirements. UCC28600 integrates built-in advanced energy saving features with high-level protection features to provide cost-effective solutions for energy-efficient power supplies. UCC28600 incorporates frequency fold-back and green-mode operation to reduce the switching losses at light-load and no-load conditions. UCC28600 is available in the 8-pin SOIC package. Operating junction temperature range is –40°C to +105°C. The UCC28600 Design Calculator, (SLVC104), located in the Tools and Software section of the UCC28600 product folder, provides a user-interactive iterative process for selecting recommended component values for an optimal design. 特性 Green-Mode Controller With Advanced Energy Saving Features Quasi-Resonant Mode Operation for Reduced EMI and Low Switching Losses (Low-Voltage Valley Switching) Low Standby Current for Minimum System No- Load Power Consumption Low Start-up Current: 25-µA Maximum Programmable Line and Load Over-Voltage Protection Internal Over-Temperature Protection Current Limit Protection Cycle-by-Cycle Power Limit Primary-Side Over-Current Hiccup Restart Mode 1-A Sink, –0.75-A Source TrueDrive™ Gate Drive Output Programmable Soft-Start Green-Mode Status Pin (PFC Disable Function) Applications Bias Supplies for LCD-Monitors, LCD-TV, PDP-TV, and Set Top Boxes AC-to-DC Adapters and Off-Line Battery Chargers Energy Efficient Power Supplies up to 200 W 相关终端应用 (18) LED 驱动器 Relay AC Analog Input Module Relay Power Supply Module 保护继电器 - 特殊功能 单相 UPS 变电站自动化 - IEC61850 过程总线 商用 DC-DC 商用 DIN 导轨电源 商用网络和服务器 PSU 太阳能 - 微型逆变器 太阳能 - 组串式逆变器 工业 AC-DC 录像机(NVR 和 DVR 等) 智能仪表 - 电表 火警控制面板 (FACP) 移动壁式充电器设计 进入控制面板 配电自动化 - 终端设备 相关型号推荐：UCC28C45DR
