Part Details for STD7N65M6 by STMicroelectronics

For USB Type-C Power Delivery adapters, optimum coherence between the QR mode flyback controller, synchronous rectification controller, and USB Type-C Power Delivery controller is critical to system performance. St has done the heavy lifting to provide a robust solution to design adapters to maximize power output for the smallest form-factor with lowest bill of material.<p>The EVLSTCH03-45WPD USB Type-C Power Delivery 3.0 adapter is a USB-IF certified solution and reference design. This evaluation board helps designers to quickly develop adapters with a short bill of materials in order to obtain a cost-effective and fast design that meets all DoE and UE CoC requirements.<p>Beyond the main silicon controllers, St also provides the main power devices and ESD protection needed for a complete hardware solution in a compact, cost-optimized design.<p>The EVLSTCH03-45WPD 45W USB Type-C® Power Delivery 3.0 adapter is a USB-IF certified solution and reference design.<p>The EVLSTCH03-45WPD is an isolated power supply with a standalone USB PD controller. The evaluation board implements at the primary side a quasi-resonant flyback converter based on the STCH03 controller with optocoupler feedback for voltage regulation. This controller combines a high performance low-voltage PWM controller chip with a 650 V HV start-up cell in the same package. The STCH03 controller drives the gate of the new 650 V MDmesh™ M6 technology Power MOSFET STD7N65M6.<p>At the secondary side, to increase the system efficiency, the rectification is based on the SRK1001 adaptive synchronous rectification controller. This controller drives the gate of the 100V STripFET™ F7 technology Power MOSFET STL110N10F7.<p>Always on the secondary side the CC/CV regulation loop to drive the power regulation stage and the USB Type-C® PD interface are based on the STUSB4761 controller. This controller offers the benefits of a full hardware USB PD stack allowing robust, deterministic and safe negotiation in line with USB PD standard.<p>The EVLSTCH03-45WPD is protected against destructive electrostatic discharge from the USB Type-C® connector using a Dual Transil array for ESD protection ESDA25L.<p>The evaluation board implements a robust adapter protected for output overvoltage, output undervoltage, output overpower and output short-circuit. This reference design, based on STMicroelectronics semiconductors, helps designers to develop adapters with a short bill of materials in order to obtain a cost-effective and fast design.
