It is best not to replace, according to what design and debugging to use what model, stability and accuracy will change after replacement.
POWER series chip is a special small power switching power control chip, output power of 3~30W, widely used in VCD\/DVD, DVB, power adapter, induction cooker, air conditioning, set-top box (village village) and other small household appliances products.
POWER series chip adopts dual-chip design, the control chip is separated from the switch tube, and is divided into different models by using different switch tubes.
The high-voltage switching tube adopts bipolar transistor design, reducing the product cost, and adopts positive and negative power supply driving in the chip, effectively protecting the safety of the switching tube
Passed ISO quality inspection and SGS environmental protection certification.
Key benefits of 22E:
1, low power consumption, no-load power consumption :0.25W;
2, wide voltage can be 80-300V;
3, has good overcurrent\/overvoltage\/overload\/short circuit\/temperature protection;
4, the ripple is less than 20 millivolts;
5, withstand pressure 700V;
6, electrostatic resistance 3800V;
7, the transformer requirements are low, and the number of coils only needs 90, which can reduce costs;
8, the peripheral circuit setup is simple.
