Characteristic Service: Copper Foot, brand-new genuine
Flyback switching power supply application:
summary:
2269 is a PWM control circuit integrated chip, which has the characteristics of low standby power consumption and low cost. It can be used in the application of offline flyback converter. Under no-load or light load conditions, the IC works in intermittent mode to reduce the loss of the application system, and can realize the functions of low standby power consumption and high conversion efficiency.
VDD has low starting current and low working current, which is conducive to the reliability design of 2269 startup. A large resistance can be designed in the application circuit to divide the voltage to start the chip.
The slope compensation function is also designed internally, which improves the stability of large signals in the system. 2269 is also internally designed with protection modules, including overcurrent protection OCP, overload protection OLP, overvoltage protection OVP, over temperature protection OTP, undervoltage locking UVLO, etc. The maximum output voltage of the gate drive can reach 18V, which protects the MOSFET. In addition, 2269 also has excellent EMI performance.
2269 is packaged with SOP-8 and DP-8.
