The ADP5303-EVALZ is a multi-featured evaluation board designed to evaluate the performance characteristics of the ADP5303D Buck DC/DC switching regulator. The board consists of two main components - a switching buck regulator power stage and a separate analog control circuit.

The buck DC/DC switching regulator power stage is designed to drive up to 1.5A of output current over an adjustable output voltage range from 0.7V to 5.5V. It features a fixed frequency PWM control scheme, providing excellent thermal and ac performance. It also provides programmable under-voltage lockout, soft-start/restart, and removable output blanking protection. It also offers a wide input voltage range from 4.5V to 28V.

The analog control section features a simple, two-resistor voltage divider to adjust the output voltage, and a voltage-controlled, overcurrent sensing circuit. It also has a free running oscillator to provide hysteresis and jitter on the control loop, improving load transient response.

The ADP5303-EVALZ evaluation board is perfect for a range of applications, including battery-powered systems, portable instrumentation, and industrial electronics. It is suitable for a wide variety of off-line DC/DC converters, AC/DC converters, transducers, detection systems, digital signal conditioning, and general industrial applications.

The board features advanced protection and monitoring features, including input power monitoring, adjustable output voltage monitoring, adjustable over-current protection, adjustable soft-start, and adjustable under-voltage lockout. It also includes a DC adapter with its input voltage selectable, which allows the board to be operated with different AC mains voltages. The board also includes over-temperature protection and thermal shutdown, and a low-power standby mode.

The evaluation board is designed to provide an easy and efficient way to evaluate the performance and efficiency of the ADP5303D integrated power supply. With its comprehensive range of input and output features, the board can accurately evaluate the performance and efficiency of the integrated power supply under different operating conditions.

In conclusion, the ADP5303-EVALZ evaluation board is a powerful tool for evaluating the performance of the ADP5303D integrated power supply. With its wide range of input and output features, and temperature protection, the board offers an excellent way to evaluate the performance of the integrated power supply under different operating conditions.
