12V 4A ac dc adapter charger with dc5.5*2.5mm

12V 4A ac dc adapter charger with dc5.5*2.5mm

Yidashun's ac dc adapter charger uses TB3865 chip. TB3865 is a highly integrated current mode PWM control chip with high performance, low standby power consumption, low cost and other characteristics. The TB3865 of our power supply has a built-in green down-conversion operating mode, which adjusts the operating frequency according to the load, reducing switching losses, thereby obtaining higher conversion efficiency with lower standby power consumption. At the same time TB3865 provides a wealth of protection, including: cycle-by-cycle over-current protection, over-voltage protection, over-voltage clamping, under-voltage latch, over-temperature protection, overload protection, and also has soft start and intermittent work mode functions. Once a fault occurs, the chip enters an automatic restart state until the fault is eliminated.
