New ProductAnnouncement AP43771H ■AP3306 APR3401 High-Power-Density Solution for 140W USB PD3.1 EPR Chargers and Adapters The AP43771H, AP3306, and APR3401 product combination provides a high-efficiency, small-footprint solution for USB PD 3.1 EPR chargers and adapters. The AP43771H is a USB Type-C® Power Delivery (PD) 3.1 decoder, compliant with USB PD specification Rev. 3.1 V1.6 Extended Power Range (EPR) 28V. This includes AVS capability of 100mV/Step support (TID - 9275). The device contains on-board MTP memory that supports system configuration customization. The AP3306 is an Active-Clamp Flyback (ACF) controller which drives a high-side PMOS and a low-side NMOS. This achieves transformer leakage energy recycling and zero voltage switching (ZVS) for high-efficiency performance. In addition, the AP3306 still achieves <30mW standby loss at high powers. The APR3401 is a secondary-side synchronous-rectification MOSFET driver optimized to work with the AP3306 in USB PD 3.1 EPR applications. The AP43771H is available in the W-DFN3030-14 (Type A1) package, the AP3306 is available in the SO-10 (Type A1) package, and the APR3401 is available in the SOT26 package. The DIODES Advantage The AP43771H, AP3306, and APR3401 combination delivers highly efficient, cost-effective, USB PD 3.1 EPR (28V) solutions for charger and adapter applications. ■ AP3306 ACF Controller Supports High-Side Switcher Drive Without Level-Shift Circuitry, and NonComplimentary High-and Low-Side Control Mechanisms Reduces Bill-of-Materials (BOM) cost and simplifies system design ■ AP43771H USB PD 3.1 EPR Decoder with 34V VCC Supports USB PD 3.1 EPR (28V) Applications and Different Forms of NVM; a) One-Time Programmable ROM for Main Firmware b) Multi-Time-Programmable ROM for User-Configuration Enables customization of system USB PD 3.1 EPR configurations ■ APR3401 Secondary-Side Synchronous-Rectification Driver Optimized for Operation with AP3306 with 45V Supply and 175V VDET (Max) Reduces BOM cost and simplifies system design The Diodes logo is a registered trademark of Diodes Incorporated in the United States and other countries.
