infineon公司的IPW60R037P7是600V CoolMOSª P7功率晶体管,组合了快速开关SJ MOSFET和极易使用的特性,其极低的开关损耗和导通损耗是得开关电源有更高的效率,更小的体积和更冷静,极好的ESD>2kV (HBM),主要用在PFC,硬开关PWM和谐振开关电源级如PC,Silverbox,适配器, LCD & PDP TV,照明,服务器,通信和UPS.本文介绍了IPW60R037P7主要特性和优势,以及3.0kW双LLC 评估板EVAL_3KW_2LLC_P7_47主要特性,电路图和数字控制板XMC4400-F64K512 AB主要特性,电路图以及PCB设计图.

The CoolMOS™ 7th generation platform is a revolutionary technology forhigh voltage power MOSFETs, designed according to the superjunction(SJ) principle and pioneered by Infineon Technologies. The 600VCoolMOS™ P7 series is the successor to the CoolMOS™ P6 series. Itcombines the benefits of a fast switching SJ MOSFET with excellent easeof use, e.g. very low ringing tendency, outstanding robustness of bodydiode against hard commutation and excellent ESD capability.

Furthermore, extremely low switching and conduction losses makeswitching applications even more efficient, more compact and muchcooler.

IPW60R037P7主要特性:

• Suitable for hard and soft switching (PFC and LLC) due to an outstandingcommutation ruggedness
• Significant reduction of switching and conduction losses
• Excellent ESD robustness >2kV (HBM) for all products
• Better RDS(on)/package products compared to competition enabled by alow RDS(on)*A (below 1Ohm*mm²)
• Large portfolio with granular RDS(on) selection qualified for a variety ofindustrial and consumer grade applications according to JEDEC (J-STD20
and JESD22)

IPW60R037P7优势:

• Ease of use and fast design-in through low ringing tendency and usageacross PFC and PWM stages
• Simplified thermal management due to low switching and conductionlosses
• Increased power density solutions enabled by using products withsmaller footprint and higher manufacturing quality due to >2 kV ESDprotection
• Suitable for a wide variety of applications and power ranges

IPW60R037P7应用:

PFC,hard switching PWM and resonant switching power stages. e.g.PC
Silverbox, Adapter, LCD & PDP TV, Lighting, Server,Telecom& UPS
