The EVM3810-QB-12-01A evaluation board is a class-two offline switching power supply, which pairs TI\'s TS3810 high power density and high efficiency residential offline flyback controller with the FA2N30S power MOSFET. Class 2 offline converters are a type of SMPS (Switched Mode Power Supply) that is ideal for low output power applications, such as consumer electronics, USB charging, and LED drivers. Class 2 converters are simple and cost-effective solutions that require minimal component count. Compared to other types of SMPS, class 2 converters offer higher efficiency, greater power density, smaller size, and lower EMI.The EVM3810-QB-12-01A evaluation board is a low power offline switching power supply with an output voltage of 12V. The input voltage range is from 89VAC to 264VAC, meaning it can operate between voltages in North America (115VAC) and the European Union (230VAC). This board provides the user with a reference design for designing a low output power offline flyback converter. The use of the TS3810 controller is made possible with the help of TI’s PowerStage™ technology, allowing for maximum power density. The wide output range of the TS3810 ensures that the design of the EVM3810-QB-12-01A is suitable for a wide range of applications.In terms of design, the EVM3810-QB-12-01A evaluation board incorporates a few main components, including a TS3810 controller, a FA2N30S power MOSFET, and an LNK450D LED driver. The TS3810 is a high density quasi-resonant buck PWM controller, which is responsible for controlling the output voltage, regulation, and current protection. It has an operating frequency of 50kHz, allowing for a power density of up to 2.4W/cm2. The FA2N30S is a high efficiency and high current density power MOSFET, which allows for high efficiency and high power density designs. Finally, the LNK450D LED driver is responsible for driving the LED string in the evaluation board.The application field for the EVM3810-QB-12-01A evaluation board includes consumer electronic accessories, TV and monitors, sensors, and general illumination. This low power offline switching power supply has an output voltage of 12V, meaning it can be used to power a wide variety of consumer electronic devices, such as mobile phones, tablets, and digital cameras. Furthermore, the wide input voltage range (from 89-264VAC) makes it suitable for worldwide applications. The LED driver in the solution can be used to power LED drivers in general illumination applications.In terms of working principle, the TS3810 controller in the EVM3810-QB-12-01A evaluation board uses a quasi-resonant topology to provide a high power density and high efficiency design. When the input voltage is applied, the controller starts switching the power MOSFET, providing the output voltage. The output voltage is then regulated by the controller, which adjusts the duty cycle of the power MOSFET switching. It also provides over-current protection, meaning it will shut off the output in the event of an overload. The LED driver then provides the LED string with the precise current needed.Overall, the EVM3810-QB-12-01A evaluation board is an ideal solution for low output power applications such as consumer electronic devices, general illumination, and USB charging. With the help of the TS3810 controller, the evaluation board is able to provide high power density and high efficiency, while the LED driver ensures that the LED string is properly supplied with the correct current. The wide input voltage range of the evaluation board makes it suitable for worldwide applications.
