Introduction

XPM5218 is a synchronous buck converter with integrated power switches, supporting USB Type-C, PD, and various other fast charging protocols. It provides a complete solution for in-car chargers, fast charging adapters, smart power strips, and other power supply applications. Supported fast charging protocols include USB Type-C and PD, Qualcomm QC2.0/3.0, Huawei FCP/SCP, Samsung AFC, USB BC1.2 DCP, and Apple 2.4A charging specification. Wide input voltage range of 6.6V to 36V. Output voltage range of 3.6V to 12V, automatically adjusted according to the charging protocol, with a maximum output power of 18W. XPM5218A PDO is configured as 5V/3A and 9V/2A; XPM5218B PDO is configured as 5V/3A, 9V/2A, and 12V/1.5A. PWM current-mode control enables fast response to load transient changes. Switching frequency of 150KHz, with proprietary frequency dithering technology to reduce EMI and help customers pass certifications. CC/CV output characteristics. When output current is below the set limit, the device operates in CV mode; when output current reaches the limit, it enters CC mode. Cable drop compensation adjusts output voltage upward as output current increases, compensating for voltage drop caused by charging cable resistance. High reliability with input voltage withstand up to 42V and ESD protection exceeding 8KV on all pins. Multiple protection features include: input OVP and UVP, output OCP, OVP, UVP, short-circuit hiccup protection, and more. ESOP8 package.
