[原创] Infineon CoolMOS C7 800W Platinum服务器电源参考设计

Infineon公司的600VCoolMOS™ C7是第五代PWM控制器,具有超低开关损耗,集成了700V和800V超结MOSFET,具有成套保护特性如输入OVP,输入欠压保护(brown in/out),引脚对GND和OTP延迟.此外还具有自动重起恢复功能,以最小化系统中断工作,主要用在服务器,电信,太阳能和工业应用.本文介绍了600 V CoolMOS™ C7主要特性和优势, 60W隔离反激SMPS应用电路以及采用600 V CoolMOS™ C7和XMC数控的800W Platinum®服务器电源主要特性和框图,主板和控制板电路图和材料清单.

The 600 V CoolMOS™ C7 series of devices offers a ~50% reduction in turn-off losses compared to the CoolMOS™ CP, offering a GaN-like level of performance in PFC, TTF and other hard-switching topologies. The CoolMOS™ C7 delivers an area-specific on-resistance (RDS(ON)*A) of just 1Ω per mm2, extending Infineon’s portfolio of products with lowest RDS(ON) per package to support customer efforts to further increase power density.

The 600 V CoolMOS C7 series features ultra-low switching losses and targets high-power SMPS applications such as server, telecom, solar and industrial applications requiring high efficiency and a reduced Bill of Materials (BOM) as well as low Total Cost of Ownership (TCO).
