ADP223CP-EVALZ Evaluation Board and Working Principle

The ADP223CP-EVALZ evaluation board is a linear voltage regulator that provides efficient regulation of output voltage from a wide range of input voltages. It is ideal for use in mobile and portable applications where battery operated devices require efficient regulation of output voltage with low power consumption. The board is designed as a low-noise, low-cost solution for voltage regulation in battery charging and other voltage regulation scenarios.

The main component of the board is the P223CP dual integrated linear voltage regulator, manufactured by Analog Devices. This two-channel device operates over a wide input voltage range, from 2.7 to 12 V. It provides advanced features, including overvoltage protection and a regulated output voltage with low dropout. Its two outputs, 5V and 3.3V, can be individually adjusted using an external voltage divider. This allows the user to achieve an efficient output voltage regulation from a wide range of input voltage levels.

The ADP223CP-EVALZ evaluation board is designed to operate with an input voltage range from 3.8V to 12V with an output voltage range from 2.7V to 12V. Its output is protected by overvoltage protection circuitry with voltage detector thresholds and voltage limiting. The board also features temperature monitoring and thermal shut-down circuitry to protect the circuit and prevent damage from over-temperature.

For input current monitoring, the board is equipped with a test point terminal for monitoring the input current. The board also features an adjustable current limiting for providing protection against overloads. The board’s output voltage is adjustable using a preset voltage divider or an external resistor divider. The board’s output current is adjustable using a potentiometer located on the top edge of the board.

The P223CP dual integrated linear voltage regulator also features a power-on reset circuit which resets the output at power-on and provides low-power and low-noise operation for efficient voltage regulation. The power-on reset circuit also provides high immunity to power-on transients. Additionally, it features soft-start technology, which starts up the regulator circuit slowly and without overshoots.

The ADP223CP-EVALZ is an efficient and cost effective solution for battery-operated applications such as portable or mobile devices. Its linear regulator makes it ideal for efficient and low-noise regulation of output voltages with a low dropout voltage. It provides overvoltage protection, temperature monitoring, current limiting, and power-on reset circuit for improved performance and protection. Its adjustable output voltage and current make it a versatile and power-efficient solution for voltage regulation.
