Overview

The CX8834B is a CC/CV step-down DC-DC converter that supports an input voltage of DC 5V-30V, a fixed output of 5V/2.4A, and features accurate constant voltage and constant current control with 100% duty cycle capability.

 

The CX8834B integrates a 70mΩ High-side PMOS and a 30mΩ Low-side NMOS, enabling a continuous output current of 2.4A.

 

The CX8834B offers excellent load transient response and line regulation. Its precise constant voltage and constant current control loops achieve extremely small load and line regulation.

 

The CX8834B requires no external compensation. It relies on its internal stable loop for constant current and constant voltage control and features a cable drop compensation function.

 

The CX8834B is an easy-to-apply, high-performance, stable, and reliable CC/CV step-down DC-DC converter.

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.
