我5块钱淘了个5V1A的,感觉应该有1A的,体积还比较小, 用的NXP的控制IC,TEA1622P
The TEA1622P is a Switched Mode Power Supply (SMPS) controller IC that operates
directly from the rectified universal mains. It is implemented in the high voltage EZ-HV™
SOI process, combined with a low voltage BICMOS process.
The device includes a high voltage power switch and a circuit for start-up directly from the
rectified mains voltage. A dedicated circuit for valley switching is built in, which makes a
very efficient slim-line electronic power-plug concept possible.
In its most basic version of application, the TEA1622P acts as a voltage source. Here, no
additional secondary electronics are required. A combined voltage and current source can
be realized with minimum costs for external components. Implementation of the
TEA1622P renders an efficient and low cost power supply system. |
