AC DC Converters

The ADNB017-24-1PM-C is a type of AC-DC converter, which is used to convert a steady, alternating current into a direct current. This converter has an input voltage ranging from 17V to 24V AC and its output is a constant voltage of 24V DC. It is also equipped with over-current, inrush current and over-temperature protection.

Application Field

The ADNB017-24-1PM-C is applicable for low-voltage, low-power applications in various industries, such as medical, industrial automation, household, communication, security, automotive and many others. Its output is suitable for DC motor drive, LED lighting, LED products, industry control devices and other equipment.

Working Principle

The ADNB017-24-1PM-C combines a buck-boost and a flyback switching regulator into a simple system. The buck-boost circuit is composed of a high frequency oscillator, an inductor, a diode, and a MOSFET switch. A MOSFET is used as the main switching element to switch between the buck-boost circuit and the DC-output circuit. The flyback function provides an isolated DC-output voltage.

The voltage regulation operates by varying the on-time of the MOSFET switch according to the measured input voltage. The DC output is rated at 24V, with a ripple voltage of less than 0.5% at its rated current. A current-mode regulating scheme is used, and the control loop is optimized for high accuracy and good line/load rejection. Inrush current limiting functionality is also included, which reduces the inrush current during power up.

Conclusion

The ADNB017-24-1PM-C is a type of AC-DC converter, used for a wide range of low-voltage, low-power applications. It combines a buck-boost and a flyback switching regulator into a simple system, and the voltage is regulated by varying the on-time of the MOSFET switch. It is also equipped with over-current, inrush current and over-temperature protection, ensuring the safety and reliability of the system.
