Switch Mode Power Supply: CoolMOS™

Infineon Technologies offers a wide range of products including high voltage MOSFETs (CoolMOS™), MOSFET driver ICs (EiceDRIVER™), control ICs Silicon Carbide Diodes (thinQ!™) for use in various PFC and PWM topologies along with low voltage MOSFETs (OptiMOS™) for synchronous rectification. With these products Infineon keeps up with the continuous increase of energy consumption and the imperative requirement for power savings.

The new 600V CoolMOS™ C7 continues the previous 650V C7 family in bringing best-in-class performance to PFC topologies, but unlike the 650V C7 it can also achieve highest efficiency in high performance in resonant topologies such as LLC. The worlds best Ron∗A (<1Ω.mm²) enables new best-in-class RDS(on)/package such as 40mΩ in TO-220. Also in combination with new innovative packages such as TO-247 4pin (using sense source concept), enables even higher efficiencies to be achieved at power >500W. The lowest Coss and Qg values of the CoolMOS™ C7 enable moving up in switching frequency without the penalty in efficiency, helping in system power density and cost challenges by reducing magnetic component size.

For low-mid power range CoolMOS™ CE, for higher power cost/performace SMPS CoolMOS™ P6 are recommended and like the 600V C7 both series are very flexible and can be used in both PFC and PWM stages.

For synchronous  rectification the OptiMOS™ series offers low on-state resistances and capacitances and can also be used with EiceDRIVER™ gate driver ICs. For PFC stage  C7 combined with SiC Gen 5 is recommended. Whereas Infineon Control ICs support topologies such as PFC, LLC and quasi-resonant flyback.

600V CoolMOS™ C7

The new 600V CoolMOS™ C7 MOSFET series from Infineon with 50% lower Eoss losses than 600V CoolMOS™ CP performing similar to GaN and brings new levels of efficiency. 600V C7 can be used in both PFC stages and high end PWM stages, helping you to bundle and cost down your designs.

40 IPP60R040C7 IPW60R040C7 IPZ60R040C7

Especially in hard switching topologies like PFC and ITTF low losses are present due to best in class RDS(on) and Eoss values, but unlike the 650V C7, the 600V CoolMOS™ C7 also performs well in soft switching topologies due to low Qoss and QG . In both the PFC and PWM stages CoolMOS™ products are the perfect fit.

Due to the lowest Coss and Qg values, CoolMOS™ C7 series enables increasing the switching frequency without penalty in efficiency. From a system perspective this means power density and BOM cost savings through use of smaller magnetic components. Moving from 65kHz to 130kHz can give material cost savings in the magnetics components of up to 30%.

Furthermore, the 600V CoolMOS™ C7 with its smaller packages and lower RDS(on) x A values (like the 40mΩ in TO-220) than any other SuperJunction MOSFET, brings benefits in scalability and modularity of designs, even for higher power range and saves your application package costs due to smaller designs.

The use of the 600V C7 technology with innovative packages such as TO-247 4pin also bring options in increasing efficiency even further or taking advantage of the combination and keeping efficiency the same but saving costs by moving up in RDS(on).

Market-Leading, Best-in-Class On-Resistance per Package

With the new 650 V CoolMOS™ C7 series, Infineon settles a new level of performance in hard-switching applications such as Power Factor Correction (PFC). It is the successor to the CP series and provides efficiency benefits across the whole load range through balancing a number of key parameters.

What does C7 offer?

30% less switching losses in comparison to its best in class predecessor CoolMOS™ CP for SMPS

100% higher robustness than our CoolMOS™ CP given the 100V/ns instead of 50V / ns

650 V was chosen to give extra safety margin for designers, making it especially suitable for SMPS. The new CoolMOS™ C7 series benefits from the 12 years manufacturing experience and continues to offer Infineon's outstanding quality.
