The EVB-EN6347QA is an evaluation board designed to assist in testing the application field and working principle of DC/DC & AC/DC (Off-Line) SMPS (SwitchMode Power Supplies). Every single component on this board has been carefully selected to provide quick and simple evaluation of the performance of the device. The board features two different outputs for AC/DC or DC/DC applications with extremely low noise levels and excellent load regulation thanks to its synchronous rectification circuit.

The board features a wide input voltage range from 85V to 265V AC, allowing it to easily fit in many different power systems. It has a maximum power rating of 80W/12V, and can provide a maximum output voltage of 24V DC, allowing it to handle a wide range of applications. The board also features synchronous rectification, which helps to reduce power dissipation and increase efficiency.

At the heart of the board is the EN6347QA monolithic controller, which provides a wide array of protection features, as well as an excellent power control capability. The built-in protections include output short circuit, overvoltage, undervoltage, over temperature, and over current. These protections help to ensure optimized performance while protecting the user from potential dangers.

The board operates by controlling the pulse width modulation of an internal power switch, which in turn controls the power output. This Pulse-Width Modulation (PWM) ensures that the load power is kept within acceptable ranges even under heavy loading, and allows the power supply to maintain a more constant output voltage as the loading changes. The board also features a programmable undervoltage lockout and overvoltage protection both adjustable via potentiometers, as well as a soft-start circuit to supply power to the system.

The EVB-EN6347QA is an excellent tool for evaluating the features of the EN6347QA and its abilities in DC/DC or AC/DC applications. With its wide input voltage capability and adjustable protections, the board makes testing and evaluation of the device easier and more reliable. Its small size and neat assembly make it an ideal choice for small or medium businesses, as well as hobbyists. It is an ideal solution for evaluation of the parameters of the EN6347QA and its performances.
