Introduction to MAXM17543EVKIT#

The MAXM17543EVKIT# is an evaluation board designed to facilitate the development of offline power supply designs. It is a complete power system for powering applications with an on-board linear regulator for system start-up and voltage supervision. The board is designed to work with a wide range of input voltages and is suitable for both low power and high power applications.The MAXM17543EVKIT# includes a control IC, the MAXM17543, which is a monolithic high-efficiency synchronous rectifier that provides an extremely high efficiency for paralleled offline power supply designs. The IC also features an integrated current-mode pulse width modulation (PWM) controller, leading-edge modulation (LEM), an auto-restart mode, fault protection features, including overcurrent protection, undervoltage lockout (UVLO), and cycle-by-cycle current limit. The MAXM17543EVKIT# can be used to develop systems that operate from a wide range of input voltages, including AC, DC, and mains AC.

Overview of Application Field and Working Principle of the MAXM17543EVKIT#

The MAXM17543EVKIT# is suitable for a variety of applications, including DC-DC converters, AC-DC converters, AC-DC adapters, desktop power supplies, and LED drivers. The board supports a wide range of input voltages including AC, DC, and mains AC.The MAXM17543EVKIT# features an integrated current-mode PWM controller, leading-edge modulation (LEM), overcurrent protection, undervoltage lockout (UVLO), and cycle-by-cycle current limit. The PWM controller enables the board to operate in a wide range of power levels, from low power to high power. The current-mode controller also ensures that the board can sustain a constant output power level over a wide range of load conditions.To operate the board, the user simply connects the input and output power, sets the output voltage, and applies the Enable switch. The Enable switch must be active before the circuit will start up and it can be latched for continuous operation. The board requires a few seconds to start up, making sure that all the protective functions are enabled before the power supply is active. When the board is in steady-state operation, it provides a seamless output with very low noise and ripple.

Conclusion

The MAXM17543EVKIT# is a highly versatile evaluation board that can be used to develop a wide range of offline power supply designs. The board features a control IC, which provides an extremely high efficiency for paralleled offline power supply designs, as well as integrated current-mode PWM, leading-edge modulation (LEM), overcurrent protection, undervoltage lockout (UVLO), and cycle-by-cycle current limit. The board is suitable for a variety of applications, including DC-DC converters, AC-DC converters, AC-DC adapters, desktop power supplies, and LED drivers.
