Evaluation Boards - Linear Voltage Regulators

The MAX8526EVKIT+ is an evaluation board designed for evaluating the performance of the MAX8526 ultra-small, low-noise, low-dropout linear regulators. The evaluation board is a low-cost solution for field-testing the MAX8526 feature set and can yield useful results in minimal time. This evaluation board provides easy connection with peripherals and a standard laboratory power supply.

Application Field

The MAX8526EVKIT+ may be used to evaluate the performance of the MAX8526 regulator in a large variety of applications. These applications can include automotive systems, consumer electronics, medical devices, networking equipment, and general-purpose industrial electronics. With its low noise, high-efficiency operation, and adjustable output voltage and current, the MAX8526 is an ideal device for a wide range of regulated power supply applications. The MAX8526EVKIT+ also provides the necessary test environment for evaluating the high-accuracy (0.95%) programming of the MAX8526 over the full load range.

Working Principle

The MAX8526EVKIT+ is designed to demonstrate the MAX8526’s performance in various operating and circuit configurations. The evaluation board uses a simple two-terminal connected quasi-linear regulator, which depends upon feedback from the output load to provide an accurate regulated output voltage. A voltage divider between the output and the error amplifier creates a negative feedback loop that maintains a constant output voltage set by external resistors. This allows the MAX8526 to meet the tight accuracy requirements of many applications.

The MAX8526EVKIT+ also includes a built-in trim function for testing the MAX8526’s internal voltage reference accuracy. The onboard potentiometer allows for +/- 2% trimming of the programmed output voltage to verify the accuracy of the internal voltage reference. In addition, the MAX8526 has included ready-to-use short-circuit protection and soft-start circuitry.

The MAX8526EVKIT+ also provides temperature protection to prevent the device from overheating and damaging itself or other parts of the system. This protection consists of an over-temperature monitor and an over-current monitor, both of which can be used to shut down the outputs and prevent damage.

Overall, the MAX8526EVKIT+ provides a comprehensive and compact solution for evaluating the performance of the ultra-small, low-noise, low-dropout linear regulators from MAXIM Integrated. Its simple setup and robust feature set make it an ideal solution for developing and testing the MAX8526’s feature set in a variety of applications.
