[原创] Infineon 2EDN7524+XMC4400 3.0kW双LLC开关电源解决方案

Infineon公司的2EDN752x/2EDN852x系列是用来驱动逻辑和正常电平MOSFET的双路驱动器,支持OptiMOSTM, CoolMOSTM,标准电平MOSFET,超级结MOSFET以及IGBT和GaN功率器件.控制输入是LV-TTL兼容,输入电压-5V到+20V,转换速率5ns,传输时延17ns,主要用在服务器SMPS,通信用SMPS,DC/DC转换器,电动工具,工业SMPS,马达控制和太阳能SMPS.本文介绍了2EDN752x/2EDN852x系列主要特性,框图,典型应用框图以及3.0kW双LLC评估板EVAL_3KW_2LLC_P7_47主要特性,主要元件分布图,电路图和PCB设计图以及HV DC/DC级主要元件.

The 2EDN752x/2EDN852x is an advanced dual-channel driver. It is suited to drive logic and normal level MOSFETsand supports OptiMOSTM, CoolMOSTM, Standard Level MOSFETs, Superjunction MOSFETs, as well as IGBTs andGaN Power devices.

The control and enable inputs are LV-TTL compatible (CMOS 3.3 V) with an input voltage range from -5 V to +20 V.-10 V input pin robustness protects the driver against latch-up or electrical overstress which can be induced byparasitic ground inductances. This greatly enhances system stability.

4.2 V and 8 V UVLO (Under Voltage Lock Out) options ensure instant MOSFET and GaN protection under abnormalconditions. Under such circumstances, this UVLO mechanism provides crucial independence from whether andwhen other supervisors circuitries detect abnormal conditions.
