• Power supply stage implementing a QR fly-back topology based on the STD7N65M6 MDmesh™ M6 primary MOSFET,

• Power control stage embedding the STCH03 primary side PWM controller with a 650 V HV start-up cell. It can operate in different

modes: QR active mode, valley skipping mode and burst mode to guarantee high efficiency at different input voltage and output load
conditions.

• Digital control stage based on the STM32G071KB Arm Cortex-M0+ MCU that manages the USB Power Delivery stack, controls the
USB Type-C connector, enables the V

BUS

and the V

CONN

power paths, and runs the adaptive synchronous rectification algorithm.

The companion TCPP01-M12 safely interface the USB-C connector with the MCU, ensuring the highest robustness and protecting

against any destructive electrostatic discharge (ESD).
