STF7N80K5 very high voltage N-channel Power MOSFETs designed using The reference design accepts a wide input mains range and delivers 5 V, 9 V and 15 MDmesh K5 technology based on an V output voltage profiles, according to the Source Power Rules of the current USB innovative proprietary vertical structure Power Delivery specification. STL40N75LF3 N-channel enhancement The adapter architecture is based on two boards: the STEVAL-USBPD45P power mode Power MOSFET produced using supply board implementing the power stage in flyback topology with synchronous STMicroelectronics STripFET III technology rectification, and the STEVAL-USBPD45I Digital Control Board designed to control the USB Type-C connector and manage the USB Power Delivery stack and the STUSB1602A USB Type-C controller adaptive synchronous rectification algorithm. (with Tx/Rx line driver and BMC) The flyback converter is based on the STCH03 offline PWM controller for low standby STM32F051 high performance 32-bit adapters and the STF7N80K5 MDmesh K5 primary MOSFET. ARM Cortex-M0 MCU On the secondary side, the adaptive synchronous rectification with STL40N75LF3 X-CUBE-USB-PD X-CUBE-USB-PD Power MOSFET is controlled and driven directly by the STM32F051 MCU, allowing software expansion for STM32Cube an overall efficiency improvement with a very low external component count. STSW-USBPD45CFW SW package for The USB type-C port is controlled by the certified STUSB1602A, enabling the VBUS STEVAL-USBPD45C reference design power path and integrating high voltage protections on VBUS and CC lines.

The chipset (STM32F051 + STUSB1602A) and relative stack X-CUBE-USB-PD running on STM32 are PD 3.0 certified. The adapter is protected against any destructive electrostatic discharge (ESD) from the USB Type-C connector by an ESDA25P35-1U1M ESD protection device which exceeds the IEC61000-4-2 Level 4 standard, offering ESD protection higher than 30 kV on the VBUS pin. This protection also provides surge immunity against electrical over stress (EOS) to prevent damage to the internal circuitry by offering up to 35 A 8/20 s protection, as per the IEC61000-4-5 standard. The adapter is designed to meet the most stringent energy saving recommendations (EU and DOE CoC ver. 5 - Tier 2). DB3575 - Rev 3 page 2/9
