The LM2743-19AEVAL evaluation board allows users to quickly evaluate the performance of the LM2743 device, which is an offline switcher controller intended for use in DC/DC, AC/DC, and SMPS applications. The board operates on either a DC or AC input voltage to achieve adjustable output voltages and is ideally suited for applications such as lighting, motor drives, battery charging, telecommunications, and power supplies. In this article, we’ll discuss the field of application and working principle of the LM2743-19AEVAL evaluation board.

The LM2743 evaluation board has a wide operating range and can be used in both DC/DC and AC/DC applications. The board is self-contained and includes the LM2743 device, an integrated gate driver, as well as a few power stage components. The onboard LM2743 device is an offline switcher controller designed to provide high efficiency and improved power factor for applications up to 100 W. The integrated gate driver allows for the use of industry-standard gate drivers, such as the UCC2722x from Texas Instruments.

The LM2743 evaluation board is designed to be used in either DC/DC or single-ended primary inductance-based (SEPIC) AC/DC applications. The board is capable of delivering an adjustable output voltage of up to 40 V and up to 3 A of output current with efficiencies of up to 88%. The board can also support loads with up to 150W peak power and can operate in a variety of different operating modes, including continuous conduction mode (CCM), discontinuous conduction mode (DCM), and skip cycle mode (SCM).

The working principle of the LM2743-19AEVAL evaluation board is based on the LM2743 device, which is a high-efficiency switch-mode power supply controller with an integrated gate driver. The board operates on either a DC or AC input voltage and is designed to deliver an adjustable output voltage of up to 40V. The device also contains an integrated gate driver, which allows for the use of external gate drivers, such as the UCC2722x from Texas Instruments. The controller operates in either CCM or DCM mode and includes hysteretic, pulse-frequency modulation (PFM), and current-mode control. The controller also features adjustable dead-time compensation, ripple control, and an internal soft-start function.

The LM2743 evaluation board includes a few power stage components, such as a buck converter, an inductor, and several capacitors. The buck converter is used to step down the input voltage to the required output voltage. The inductor is used to store energy and is connected to the output of the buck converter. The capacitors provide energy storage and filter the ripple on the output of the buck converter. The LM2743 device also contains several features such as dead time control, soft-start, ripple control, and adjustable hysteresis, which help to optimize the overall efficiency, transient response, and system stability.

The LM2743-19AEVAL evaluation board is a great way to quickly evaluate the performance of the LM2743 device in DC/DC, AC/DC, and SMPS applications. The self-contained board operates on either a DC or AC voltage and can deliver an adjustable output voltage up to 40V and up to 3A current. The LM2743 device contains several features such as dead time control, soft-start, ripple control, and adjustable hysteresis, which help to optimize the overall efficiency, transient response, and system stability.
