Infineon 2EDF7275F 3300W CCM双向图腾柱PFC解决方案
Infineon公司的EiceDRIVER™ 2Edi系列产品是双路隔离MOSFET栅极驱动器,通过无芯变压器(CT)技术提供功能(2EDFx)或增强(2EDSx)输入/输出隔离.由于具有高驱动电流,极好的共模抑制和快速信号传输,2EDi系列特别适用于驱动快速开关电源系统的中压到高压MOSFET (CoolMOS™, OptiMOS™, CoolSIC™).源/沉输出电流为4A/8A或1A/2A,高达10MHz PWM开关频率,PWM信奉传输时延典型值为37ns:通路到通路不匹配为3ns,传输时延变化为+7/-6ns.电阻可编程死区控制(DTC)范围从15ns到250ns.共模瞬态免疫度CMTI大于150V/ns,输入边欠压锁住(UVLO)情况下快速安全关断,4V或8V UVLO阈值输出电压从4.5V到20V,工作温度TJ = -40C 到 +150C.主要用在服务器,通信和工业SMPS,同步整流,砖型转换器,UPS和电池存储,以EV充电工业自动化,马达驱动和电动工具.本文介绍了2EDF7275F主要特性,框图,应用电路,以及3300W CCM双向图腾柱评估板EVAL_3K3W_TP_PFC_SIC主要特性,主板和控制板电路图,材料清单和PCB设计图.
The EiceDRIVER™ 2EDi is a family of fast dual-channel isolated MOSFET gate-driver ICs providing functional (2EDFx) or reinforced (2EDSx) input-to-output isolation by means of coreless transformer (CT) technology. Due to high driving current, excellent common-mode rejection and fast signal propagation, 2EDi is particularly well suited for driving medium- to high-voltage MOSFETs (CoolMOS™, OptiMOS™, CoolSIC™) in fast-switching power systems.
