DC/DC & AC/DC (Off-Line) SMPS (Switched Mode Power Supplies) products provide power conversion solutions for applications that require enhanced energy efficiency and high levels of flexibility. The ADP2121-2.3-EVALZ is an evaluation board designed for DC/DC & AC/DC (Off-Line) SMPS driven by an integrated power switch controller IC that supports pulse width modulation (PWM) control for a wide range of output voltage and current configurations.

The application field of the ADP2121-2.3-EVALZ includes applications such as consumer electronics, commercial lighting, telcos, industrial and medical applications, and the automotive industry. As a universal evaluation platform for DC/DC & AC/DC (Off-Line) SMPS applications, the ADP2121-2.3-EVALZ helps developers to quickly evaluate the capabilities of the controller IC and the board in realistic operating conditions.

The main features of the ADP2121-2.3-EVALZ are its integrated power switch controller, its adjustable input voltage range, its adjustable output voltage range, and its high efficiency. The integrated power switch controller provides a high switching frequency with low ripple output voltage, making the board suitable for a wide range of applications.

The adjustable input voltage range of the ADP2121-2.3-EVALZ board is from 85-265VAC, making it suitable for global mains applications. The adjustable output voltage range is from 0-28V with a programmable maximum current output of up to 1.5A. The board also features a wide operating temperature range from -45℃ to +85℃.

The ADP2121-2.3-EVALZ board is designed to offer an excellent power conversion efficiency, and is capable of achieving more than 85% efficiency. This high efficiency allows the board to consume less power and generate less waste heat, resulting in improved overall system efficiency and reliability.

The working principle of the ADP2121-2.3-EVALZ board is based on PWM control. PWM is used to control the on/off semiconductor switches such as MOSFETs in the power stage. The output voltage of the board is determined by the duty cycle of the PWM pulse, where the duty cycle is the ratio of the ON time of the MOSFET switches versus the total time.

The PWM signal is generated by the integrated controller IC which is responsible for setting the output voltage of the ADP2121-2.3-EVALZ board. This IC also allows the board to be set up in either continuous or discontinuous conduction mode depending on the system design requirements.

In continuous conduction mode, the output current is continuous when the MOSFET switches are ON. The maximum power available in this mode is limited by the maximum switching frequency of the controller IC. In discontinuous conduction mode, the output current is allowed to go to zero during each PWM cycle, thereby allowing higher power loads to be driven by the board.

The ADP2121-2.3-EVALZ is an ideal evaluation platform that helps designers evaluate the performance of their DC/DC & AC/DC (Off-Line) SMPS designs. With its adjustable input and output voltage range, its high efficiency and its integrated power switch controller, the board provides the flexibility and performance needed for a wide range of applications.
