PMIC - AC DC Converters, Offline Switchers

The AP3983BMTR-G1 is an integrated AC/DC converter and offline switcher, which is widely used in industrial and general purpose power conversion applications, particularly in automotive systems. The device combines a high performance DC/DC converter and a low quiescent current offline switching regulator in a compact package, allowing for ease of system integration.The AP3983BMTR-G1 features an integrated protection circuit that provides protection for over-voltage, over-temperature and over-current conditions. It also features an independent shutdown input to enable the user to manually disable the output of the device in the event of a fault.The AC/DC converter provides high efficiency power conversion from an AC input voltage of up to 48 VDC into a current limited output voltage of 12 VDC, at a maximum current of 5 A. The AC/DC converter utilizes a MOSFET power switch operating in fixed frequency and uses primary-side voltage feed back to detect the output voltage and current.The AP3983BMTR-G1 also incorporates an offline switching regulator with an integrated switching power stage, allowing the user to run the device with a minimum supply voltage of 18 V. This device is capable of providing up to 500 mA of current delivery with a minimum output voltage of 0.9 V. The device is protected from over current and over temperature conditions by its integrated protection circuits.The AP3983BMTR-G1 is designed to provide a high level of performance, reliability and ease of integration for general purpose or automotive applications. The device is suitable for a wide range of applications, such as automotive systems, industrial equipment, consumer electronics, lighting and general AC/DC power conversion.Power conversion from an AC line input to a DC output can be achieved in several ways. The most popular approach is the use of a switch-mode power supply (SMPS). This type of power supply uses a high frequency switching network to provide a low ripple output voltage, while achieving high efficiency and a low level of harmonic distortion.The AP3983BMTR-G1 is an SMPS, utilizing a high frequency, fixed frequency power switch. The power switch operates in either an open loop or closed loop mode, as determined by an internal control circuit. In an open loop configuration, the switching frequency is set by the user and remains constant, while in a closed loop configuration, the switching frequency is dynamically adjusted based on the output voltage to achieve the desired output power.The AP3983BMTR-G1 also features an integrated protection circuit that provides protection against inrush current, reverse current, over temperature and over-voltage conditions. The integrated protection circuits are designed to ensure safe operation in a wide range of environmental conditions.The design of the AP3983BMTR-G1 allows for easy integration into existing power systems. The device is also compatible with a variety of control and diagnostic systems, allowing for excellent system performance in a wide range of applications. In addition, the device can easily be configured to accommodate different line voltages, output voltage, current and switching frequencies.The AP3983BMTR-G1 is an excellent choice for a wide range of AC/DC conversion applications, in both industrial and consumer applications. Its combination of a high performance DC/DC converter and offline switcher in a compact package, along with its integrated protection circuits and easy system integration, make it an ideal solution for a variety of power conversion requirements.
