PWM flyback controller with integrated MOSFET

Featured Product from Infineon Technologies AG

In tandem with Infineon’s leadership in the area of high voltage superjunction MOSFETs, the latest 700 V and 800 V CoolMOSTM P7 families will be integrated together with the 5th generation controller in a single package. CoolSETTM is available in both through-hole and SMD packages and thereby eliminates the need of heatsink and reduces BOM count with a small footprint.
