When it comes to evaluation boards, DC/DC & AC/DC (Off-Line) SMPS and ADP1871-1.0-EVALZ are two names that stand out. ADP1871-1.0-EVALZ is the evaluation board for the ADP1871-1.0 DC/DC & AC/DC (Off-Line) SMPS integrated circuits with intelligent power supply control IC, developed by ADI company. This evaluation board helps engineers evaluate and verify the performance of the ADP1871-1.0-EVALZ and other DC/DC & AC/DC (Off-Line) SMPS in a variety of environments.

ADP1871-1.0-EVALZ board is a comprehensive board that incorporates several DC/DC & AC/DC (Off-Line) SMPS circuit design solutions for engineers and designers. It helps customers to evaluate and verify their own designs with this board. The ADP1871-1.0-EVALZ evaluation board is a compact and user-friendly design platform that allows engineers to quickly evaluate the performance of the ICs without the need to set up breadboards.

The evaluation board presents a ready-to-use printer power supply for off-line SMPS applications. It consists of a switching power supply main controller IC, ADP1871-1.0, and related external power components. It has several design options available in the application field, which are printer, fax machine, copier and Ethernet POE supply.

The working principle of the ADP1871-1.0-EVALZ evaluation board is based on the design concept of active power factor correction (PFC). Active PFC improves the power factor of most off-line AC/DC converters from its native 85% to below -95%. The ADP1871-1.0-EVALZ employs a hysteretic mode PFC control to achieve the pre-defined power factor. This provides high levels of power conversion efficiency and low standby losses.

The key component of ADP1871-1.0-EVALZ is the ADP1871-1.0 IC. This IC is a high power density controller, which includes a high voltage MOSFET and all the necessary functions for an off-line SMPS application. It has flexible protection features that can detect and limit over-current and power-failure conditions. It also has other features such as an LED backlight control and programmable soft start.

The external circuitry of the ADP1871-1.0-EVALZ board includes the filter system, bridge rectifier, and transformer that are used to provide the isolation and step-up the primary side power. The external components used are thermally protected and designed in an unrestricted format in order to allow easy assembly. The filter components used provide a minimum of 68 dB of attenuation and a noise figure of less than 0.1%.

The ADP1871-1.0-EVALZ evaluation board has easy-to-use features that enable users to program the IC and adjust different parameters such as soft start time, PFC duty cycle, and system power efficiency. It also offers protection features such as over-current protection, thermal foldback current limit, and output short-circuit protection.

ADP1871-1.0-EVALZ is a perfect evaluation board for DC/DC & AC/DC (Off-Line) SMPS applications. It provides engineers and designers with an easy-to-use platform to evaluate the performance of the ADP1871-1.0 IC and other DC/DC & AC/DC (Off-Line) SMPS. It offers a wide range of options for engineers and designers, and helps them get the most out of their designs. Furthermore, its active PFC control helps boost efficiency and protect circuit components against over-current conditions.
