Overview

The CX8901X series are wide-input voltage switching buck DC-DC controllers supporting input voltages up to 120V.

The CX8901X features low standby power consumption, high efficiency, low ripple, and excellent bus voltage regulation and load regulation.

The CX8901X supports high-current output, capable of delivering over 10A.

The output voltage can be set by configuring the voltage divider resistors on the FB pin.

The CX8901X series employs fixed-frequency PWM control with a typical switching frequency of 100kHz. It enters skip-cycle mode during light loads to achieve high conversion efficiency. The CX8901X series integrates soft-start, over-temperature protection, output short-circuit protection, current limiting, and cycle-by-cycle current detection internally, enhancing system reliability. Packaged in ESOP-8L, the CX8901X series features minimal external components and is ideal for wide-input, high-power DC-DC buck applications.

CX7539F

CX7539F is a high-performance synchronous rectification control circuit for the secondary side of switching power supply. In the application of low-voltage and high-current switching power supply, it can easily meet the energy efficiency of class 6, and is an ideal solution for ultra-low conduction voltage drop rectifier devices. The chip can support switching frequency applications as high as 150kHz, as well as switching power mode applications such as CCM/QR/DCM. The loss caused by its extremely low turn-on voltage drop is far less than the turn-on loss of Schottky diode, which greatly improves the conversion efficiency of the system and greatly reduces the temperature of the rectifier device.<br/><br/>CX7539F is a synchronous rectifier switch with built-in high voltage NMOSFET, and it has extremely low internal resistance, which can provide the application output of the system up to 5 years. IC determines the switching state of integrated MOSFET by detecting its source-drain voltage, which is compatible with flyback converters in continuous mode, discontinuous mode and quasi-resonant mode.<br/><br/>CX7539F adopts special self-power supply technology, which can ensure that the chip will not work under voltage in both constant current and constant voltage working states of the primary control system.
