Summary
●The CX7530 is a high-performance multi-mode PWM flyback controller. This product is convenient for users to design high-performance AC/DC conversion switching power supply with less peripheral components and lower system cost.
●The CX7530 provides intelligent protection functions with excellent performance, including periodic over-current protection, overload protection, soft start, chip over-temperature protection, VDD under-voltage locking protection, and VDD over-voltage locking protection.
●The CX7530 chip has the function of automatically recognizing the load size and automatically adjusting the working mode. Under the condition of full load or heavy load, the chip works at a fixed frequency of 65KHz. When the load is reduced, the operating frequency of the chip is reduced, effectively reducing the switching loss. When the load is under extremely light load or no-load condition, the chip is in interval mode.
●The CX7530 has built-in intelligent frequency dithering technology, which not only reduces the electromagnetic interference generated by the system in the frequency reduction mode, but also effectively reduces the output ripple. The unique working mode of the chip minimizes the audio energy and has no audio noise.
●The CX7530 is packaged with SOP-8L, which provides a good design platform for flyback switching power supply systems requiring ultra-low standby power consumption.
