IP6525S Description:
IP6525S is an integrated synchronous switch step-down converter that supports multiple output fast charging protocols, providing a complete solution for car chargers, fast charging adapters, and intelligent plug and play.
IP6525S has a built-in power MOS, with an input voltage range of 5.2V to 32V and an output voltage range of 3V to 12V. It can provide a maximum output power of 22.5W and automatically adjust the output voltage and current according to the recognized fast charging protocol. Typical output voltages and currents include 5V/3.4A, 9V/2.0A, and 12V/1.5A.
IP6525S has an automatic overcurrent point adjustment function. When the SCP and low-voltage fast charging protocol handshake is successful, it supports 5V/4.5A and 4.5V/5A.
The output voltage of IP6525S comes with a wire compensation function. As the output current increases, the output voltage will correspondingly increase to compensate for the voltage drop caused by the impedance of the connecting wire.
IP6525S has a soft start function, which can prevent the impact current during startup from affecting the stability of the input power supply.
IP6525S integrates fast charging protocol, which can automatically identify the fast charging protocol supported by the output terminal connected device through DP/DM, and then automatically adjust the output voltage and current. The fast charging protocols supported by IP6525S include DCP (Apple and BC1.2), Qualcomm QC2.0/QC3.0, Huawei Fast Charging Protocol FCP, Samsung Fast Charging Protocol AFC (MAX 12V), MTK Fast Charging Protocol, Spreadtrum Fast Charging Protocol SFCP, and OPPO Fast Charging Protocol VOOC.
IP6525S has multiple protection functions, including input overvoltage and undervoltage protection, output overcurrent, overvoltage, undervoltage, short circuit protection, etc
IP6525S adopts ESOP8 packaging.

IP6525S Typical application schematic:
explain:
1. The EPAD of IP6525S must have good contact with the GND of the PCB board.
If HLED indicator light is not needed, PIN4 cannot be connected anywhere and can be suspended.
3. C1 and C2 should be placed near PIN7;
4. C5 should be placed near PIN8;
5. The RC circuit composed of R1 and C6 should be placed near PIN2, and the loop formed by the SW and GND of the RC circuit and IC should have the smallest area on the PCB;
