Evaluation boards are a great way to determine the ideal parameters, features and performance of a certain equipment, such as a linear voltage regulator.

The ADP7112CB-EVALZ is a simple Regulated Multiple Output Linear Voltage Regulator Evaluation Board geared towards developing high efficiency, extremely low noise power supplies for applications requiring accurate voltage and current regulation. It is specifically designed to provide flexibility by selecting from a variety of input and output voltages.

The application field of the ADP7112CB-EVALZ is suitable for a variety of analog and digital applications such as precision instrumentation application requiring ±5V and/or 3.3V supplies, system and peripheral card supply sourcing, distributed supply rails in control or automation systems, FPGAs and digital signal processors. Additionally, the board can be used for testing and validating power supplies for medical equipment, and battery-powered systems.

ADP7112CB-EVALZ is based on a single switch-mode switching regulator IC and it uses sync-rectified topology to provide high efficiency, low noise and wide output regulation range. It provides the flexibility of having selectable input voltage (12V-19V), dual ±5V output (±3A), and 3.3V output (up to 8A).

The ADP7112CB-EVALZ provides a wide input voltage range, namely, 8-19V. This enables the board to work with a wide range of power sources. Its’ output voltage is adjustable via an external user-controllable signal, allowing the user to adjust the output voltage as needed. Additionally, the board features over-current and overtemperature protection, as well as short-circuit protection and current-limiting, ensuring proper operation and helping to protect the board from damage in the event of overload.

The working principle of the ADP7112CB-EVALZ is based on the switch-mode switching regulator technology. A switching regulator controls a power supply by varying the duty cycle of a high-frequency power switch, to maintain a nominal output voltage. It works by allowing the voltage source to switch rapidly between two different values (high and low). The higher the duty cycle, the higher the output voltage. This allows the regulator to maintain a stable output voltage even in situations where the input voltage is changing.

The ADP7112CB-EVALZ is designed with a built-in current-mode control loop, achieving excellent line and load regulation, low ripple, and good stability. It also features an adjustable on-time control loop, allowing the user to adjust the output voltage as desired. This helps to ensure a continuous and reliable output voltage even under varying conditions.

In summary, the ADP7112CB-EVALZ is an ideal evaluation board for customers requiring a reliable linear voltage regulator. It provides a wide operating range and features multiple protection functions, allowing it to be used as a reliable and durable power source for a variety of applications.
