Summary:
CX7530C is a high-performance multi-mode PWM flyback control. This product facilitates users to design high-performance AC/DC conversion switching power supplies with fewer peripheral components and lower system costs.
CX7530C provides extremely comprehensive and high-performance intelligent protection functions, including cycle by cycle overcurrent protection, overload protection, soft start, chip over temperature protection, VDD undervoltage locking protection, and VDO overvoltage locking protection.
CX7530C chip has the function of automatically identifying the size of the load and adjusting the working mode. Under full or heavy load conditions, the chip operates at a fixed frequency of 65KHZ. When the load is reduced, the operating frequency of the chip decreases, effectively reducing switch losses. When the load is under light or empty load conditions, the chip is in interval mode.
CX7530C is equipped with intelligent frequency jitter technology, which not only reduces the electromagnetic interference generated by the system in frequency reduction mode, but also effectively reduces output ripple The unique working mode of the chip minimizes audio energy and eliminates audio noise.
CX7530C adopts SOP-8 packaging, providing a good design platform for high cost performance flyback switching power supply systems that require ultra-low standby power consumption.
