Description

IP6520 is an integrated synchronous buck converter with built-in power MOSFETs, designed for fast-charging applications. It supports multiple fast-charge output protocols, including USB Type-C, USB PD2.0, PD3.0 (PPS), and mainstream proprietary fast-charge standards. It delivers a complete solution for car chargers, fast-charging adapters, and smart power strips. The device operates over a wide input voltage range of 7.1V to 32V and provides an adjustable output voltage from 3V to 12V, with a maximum output power of 20W. Based on the detected fast-charge protocol, IP6520 automatically adjusts output voltage and current. Typical output profiles include 5V/3A, 9V/2.22A, and 12V/1.67A. IP6520’s PD output features CV/CC regulation. When output current is below the set limit, it operates in constant-voltage mode. When the load current exceeds the limit, it switches to constant-current mode and reduces the output voltage accordingly. The device includes automatic over-current point adjustment. After successful high-voltage SCP negotiation, it supports up to 10V/2.5A output. When a connected Type-C device supports Huawei high-voltage SCP, IP6520 prioritizes SCP over PD to achieve higher charging power. To compensate for voltage drop caused by cable resistance, IP6520 incorporates line voltage compensation, increasing output voltage as load current rises. A soft-start function limits inrush current during startup, improving input power stability. IP6520 supports Type-C output and integrates multiple fast-charge protocols. It automatically detects the connected device via CC1/CC2 or DP/DM and adjusts output accordingly. Supported protocols include DCP (Apple & BC1.2), Qualcomm QC2.0/QC3.0, Huawei FCP & high-voltage SCP, Samsung AFC (up to 12V), and USB PD2.0 / PD3.0 (PPS). Comprehensive protection features are built in, including input over-voltage and under-voltage protection, as well as output over-current, over-voltage, under-voltage, and short-circuit protection. IP6520 is available in a compact ESOP-8 package, making it suitable for space-constrained fast-charging designs.
