12V 3.75A 4PIN 45W power supply LCD

12V 3.75A 4PIN 45W power supply LCD

100% brand new and high quality,all our 45w power supply products are CE / FCC / RoHS certified,pls do not worry.Under normal operating conditions of ac dc power supply, the duty cycle of the power MOSFET decreases linearly with the increase in the current of the control pin, that is, the pin has the previous 3 terminals and becomes the current 7 pins, which is the TO-220-7C kind. The power adapter efficiency can also be adjusted higher. It will not be very high at about 85%. It depends on your output. Similar to TO225Y, TOP255YN is also an integrated switching power supply chip, which can convert the input current of the control pin into the duty cycle of the output of the high-voltage power MOSFET switch. For the set output voltage, a smaller transformer core and / or a higher transformer primary inductance can be used. Reduce TOPSwitch power consumption while avoiding saturation of the transformer core during startup and output transients.
