The DC2190A-A is an evaluation board designed for off-line flyback switch mode power supply applications. This evaluation board is a versatile and efficient platform for application development and testing for applications such as industrial, automotive, medical, and IT. It is designed with an integrated dual-channel boost converter, a high-side MOSFET, an N-Channel MOSFET, two synchronous rectifiers, and a passive PFC controller.

The DC2190A-A’s integrated dual-channel boost converter provides an efficient route for implementing flyback SMPS application by allowing a single switching regulator to be used to generate both the high and low voltages. The integrated high-side MOSFET provides the high-side voltage switching while the integrated N-Channel MOSFET provides the low-side voltage switching. The dual-channel boost converter gives designers the ability to control both the high and low-side switches independently for improved efficiency and flexible control over output voltages.

The integrated synchronous rectifiers and PFC controller provide excellent EMI and power line. The synchronous rectifiers rectify the AC waveform into a DC output, while the PFC controller eliminates power surges and noise on the input power lines. This provides an efficient and reliable power supply for applications that require low EMI and power line noise.

The DC2190A-A also offers a wide range of protection features including an adjustable under voltage lockout, short circuit protection, thermal overload protection, and overvoltage protection. The adjustable under voltage lockout prevents the device from starting up when the supply voltage is not within the device’s operating voltage range. The short circuit protection prevents the output voltage from exceeding the output voltage limit. The thermal overload protection is triggered when the power dissipation exceeds the rated power dissipation of the device, and the overvoltage protection limits the output voltage to a safe level.

In addition, the DC2190A-A offers a wide range of protection features, including adjustable under voltage, short circuit protection and thermal overload. It also has a full range of digital and analog control pins for easy customization. The board features an external oscillator for precise frequency control, a programmable soft-start function, and an adjustable switching frequency for optimized to output efficiency. The DC2190A-A evaluation board allows users to quickly and easily evaluate and develop their applications.

Overall, the DC2190A-A evaluation board offers a versatile, efficient and reliable solution for switch mode power supply applications. It is a great platform for application development and testing for wide range of industrial, automotive, medical, and IT applications. With its integrated dual-channel boost converter, high-side MOSFET, N-channel MOSFET, synchronous rectifiers and PFC controller, the DC2190A-A provides excellent EMI and power line noise performance. Its various protection features, such as adjustable under voltage, short circuit protection and thermal overload protection, ensure safe operation. Finally, the board offers a wide range of digital and analog control pins for easy customization, making it an excellent platform for evaluation and development.
