AC DC converters are integral components of almost all of today’s electronic designs. This type of device is responsible for converting alternating current (AC) to direct current (DC) for the purpose of powering all kinds of electronic devices. It is critical for everyday electronic application which need a DC power supply that works in a wide range of input voltage. One of the most popular AC/DC converters is the SPD482401. This article will explain the application field and work principle SPD482401.

SPD482401 Application Field:

The SPD482401 is a highly versatile AC/DC controller and features a wide range of applications in the field of electronics. It is mainly used for medium power applications which typically range from 75W-600W. It is widely used for products such as LED lighting, wireless charger, USB-PD and consumer-power supply applications. Other applications of SPD482401 include industrial and home appliances, UPS systems, and adapter applications.

The SPD482401 offers a high degree of flexibility due to its high power factor that is well suited for applications that require compliance with the latest ENERGY STAR® and other regulations. Moreover, the SPD482401 is an excellent solution for applications that require external components due to the integrated controllers and little need for complicated compensation and loop stabilization.

SPD482401 Working Principle:

The SPD482401 is a high-performance, multi-mode, multi-topology, offline AC/DC converter with adjustable peak current. It regulates the input voltage and current by manipulating the applied voltage or current fields to achieve the desired output voltage and current. This includes three standard topologies – bridgeless PFC, buck and boost. It is capable of both voltage and current regulation.

The SPD482401 also integrates a complete, sophisticated controller into a single IC. It consists of a Peak Current Control (PCC) architecture and a Volatile Pulse-Width Modulation (V-PWM) control architecture featuring an adjustable peak current and frequency. This makes it easy to adjust the peak current and frequency of the output waveform.

In addition to the PCC and V-PWM control architectures, the SPD482401 also incorporates an active gate driver and an external resistor divider for setting the input voltage and over-voltage protection levels.

The SPD482401 provides excellent performance with low power dissipation, low noise, and high power efficiency. It also integrates an advanced slope compensation stage that can protect the system from multiple shock and transient input conditions.

Conclusion:

The SPD482401 AC/DC converter is highly versatile and can be easily tailored to an assortment of applications. Its integrated controllers, high power factor, low power dissipation, and advanced slope compensation make it the ideal solution for medium power applications. By understanding the application fields and the working principle of the SPD482401, users can quickly select and integrate it into their system.
