With the development of technology, smps(switch mode power supply) is becoming increasingly important, as electronic products must often work reliably in different environments. To meet this demand, a new type of smps - EA4529YH-T0011 - was released. This article will discuss in detail the application field and working principle of EA4529YH-T0011.

EA4529YH-T0011 is a high reliability, low standby power consumption evaluation board based on the TOP250G-T2 off-line swithc mode power supply controller. It is mainly used for negative output applications such as computer adapters, communication sets, LED illumination products and lighting applications. The input voltage ranges from 85Vac to 265Vac, and the output is adjustable between 0.5V and 15V at a load current up to 2A. It\'s efficiency is up to 88%.

The working principle of EA4529YH-T0011 is fairly simple. At the input side, the device takes the AC voltage from the mains and converts it to DC. Then, a high frequency oscillator in the controller starts to switch and operates at a constant frequency to control the rectified DC voltage. The energy stored in an inductor is quickly released during each switch cycle, converting it to a high frequency PWM output. The PWM output is regulated through an adjustable feedback voltage and will be converted to a DC voltage with an output filter. This DC voltage is used to power the device.

Apart from the applications mentioned above, EA4529YH-T0011 can also be used in mobile chargers and adapters, digital cameras and other low power circuit applications. The device is designed to meet all electromagnetic regulations, such as CISPR32, EN55022, FCC, etc., making it applicable to most stringent global safety requirements.

In conclusion, EA4529YH-T0011 is a reliable and efficient evaluation board based on TOP250G-T2 off-line switch mode power supply controller. It can be used in negative output applications such as computer adapters and LED illumination products, and offers excellent performance in terms of reliability, efficiency and compliance with global safety requirements.
