IRU3047CWTR is a highly advanced IC module designed by International Rectifier with integrated fast diode and ESD protection, which can be used in power management applications such as fast/slotted switching converters and DC/DC/AC converters. Its wide operating voltage range (60V-200V) makes it an ideal choice for a variety of power application fields. In terms of the application field and working principle of the IRU3047CWTR, it can be classified in the PMIC (Power Management IC) category under Voltage Regulators, with the specific sub-category of Linear + Switching.

The IRU3047CWTR Voltage Regulator is made up of a Magnetic Switch Controller (MSC), a Pulse Width Modulation (PWM) Control, a Synchronous Rectification Controller (SRC) and a Set Point Regulator Generator (SRG). It is designed to provide a high current, stable, reliable output when operating from a wide input range. It is designed to provide a broad range of adjustable output voltages from 0.5V to 200V, making it ideal for a variety of different applications.

The IRU3047CWTR’s switching regulator controller is part of the magnetic switch controller (MSC) which is composed of a dedicated control logic and an integrated power control FET. It features a family of MSCs that provide a wide range of power levels to various applications. The MSC also includes protection features such as over-voltage shutdown and over-current protection. In addition, the MSC includes a low power mode which allows the device to be powered down when not in use.

The PWM control which is the Pulse Width Modulation (PWM) control which is the primary function of the IRU3047CWTR Voltage Regulator. PWM is used to control the power conversion from dc to ac, using the set point and switching frequency. The output of the PWM is then passed to the MSC for current regulation and to the SRG for voltage regulation. The SRG also provides an adjustable voltage regulation and variable output current regulation for different applications. In addition, the SRG has an adjustable open loop response time of 2 to 20ms.

The Synchronous Rectification Controller (SRC) provides an improved power efficiency and reduced total harmonic distortion which is ideal for High Efficiency DC/DC converters. This controller also manage peak current up to 200A, with protection features such as short circuit and over-temperature protection. It also has adjustable burst mode and duty cycle control.

In conclusion, the IRU3047CWTR Voltage Regulator offers a versatile and highly efficient solution for a wide range of power management applications. Its wide input voltage range and adjustable output voltages make it ideal for many applications. Its additional protection features ensure reliable and safe operation. Finally, its integration of fast diode and ESD protection provide added assurance and reliability in challenging conditions.
