Overview:

QC3.0/FCP/AFC fast charging protocol controller recommendation CX601

CX601 is a USB port fast charging protocol control chip. Intelligent recognition of multiple fast charging protocols for fast charging of mobile phones and other powered devices. CX601 can accurately adjust the VBUS output voltage based on the voltage request sent by the receiving device, thereby achieving fast charging.

CX601 will automatically detect whether the connected device supports the Apple Fast Charge Protocol before adjusting the 5V output voltage. If supported, Apple devices will charge at maximum current. If not, it will continue to check if it supports the voltage regulation fast charging protocol. If the connected device does not support the voltage regulation fast charging protocol, CX601 will prohibit output voltage adjustment and configure the power supply device as USB DCP to ensure the safety of the powered device and obtain maximum current charging. If the voltage regulation fast charging protocol is supported, start accepting request instructions for output voltage adjustment.

CX601 can pass QC_ EN enables or disables the high-voltage fast charging function, making applications more flexible.

CX7538BS

CX7538BS is a high-performance secondary side synchronous rectification control circuit for switch-mode power <br/><br/>supplies. It easily meets the Level VI energy efficiency requirements in low-voltage, high-current switch-mode power <br/><br/>supply applications, making it an ideal solution for ultra-low forward voltage drop rectification devices. It also supports <br/><br/>various operating modes of switch-mode power supplies, such as CCM, QR , and DCM . Its extremely low forward <br/><br/>voltage drop results in much less conduction loss compared to Schottky diodes, greatly improving the system's <br/><br/>conversion efficiency and significantly reducing the temperature of the rectification device.<br/><br/><br/><br/>The CX7538BS chip features an NMOSFET synchronous rectification switch with a built-in voltage tolerance of 60V <br/><br/>and an extremely low internal resistance, with a typical RdsON as low as 12mΩ, providing the system with an output <br/><br/>capability up to 4A. The chip determines its switching state by detecting the source-drain voltage of the built-in <br/><br/>MOSFET, making it compatible with flyback converters in continuous mode, discontinuous mode, and quasi-resonant <br/><br/>operation modes.
