Overview

The CX8576Q is a high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated high-side and low-side power MOSFETs. With a wide input range from 4.75V to 36V, the converter can deliver an output voltage ranging from 0.8V to VIN with up to 4.8A continuous output current. The converter can be configured as a single output with independent constant current (CC) regulation. In the event of output overload or short-circuit, other protection features include cycle-by-cycle current limit, input under and over voltage protection, and thermal shutdown. The CX8576Q also provides programmable cable voltage drop compensation by selecting an appropriate external resistor divider. The switching frequency is internally set to 110kHz.

The CX8576Q is available in a QFN20L-5x5 package.

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.
