IRU3037CSTRPBF is a DC-DC switching controller developed by Infineon Technologies. It is used to provide energy efficiency in a wide range of power supply designs ranging from 5V to 48V. This switching controller is designed to provide excellent load regulation, fast load transient response and load disconnect feature with very low system noise. IRU3037CSTRPBF also has the capability to provide an output voltage with or without synchronization to PFC controller.
Applications of the IRU3037CSTRPBF include: industrial and telecom power supplies, severs, datacom, automotive applications, and LED drivers. This switching controller is especially suitable for applications where high efficiency and low system noise are desired. It also works well for high current applications with rotating fields and drives.
The IRU3037CSTRPBF is configurable and offers several advanced features. These features include programmable switching frequency, programmable output voltage, programmable slew rate, over-voltage protection, over-current protection, thermal shutdown protection, cycle-by-cycle current limit protection, and an integrated bootstrap diode. This switching controller also has a watchdog timer to monitor internal operations and detect any anomalies.
The working principle of the IRU3037CSTRPBF is based on buck-converter topology. This buck converter is an electrical circuit that converts electrical energy from one form to another. It consists of an input signal, a switch, an inductor, a diode, an output capacitor and a signal injection circuit. The input signal is connected to the switch which is usually a MOSFET or transistor. The switch is opened and closed depending on the signal from the control logic and the input voltage. The inductor is charged and discharged when the switch is opened and closed, and the output capacitor filters out the ripple resulting in smooth output voltage.
The signal injection circuit is used to provide feedback control of the output voltage. The output voltage is monitored by the feedback voltage and compared to the reference voltage. When the output voltage is higher than the reference voltage, the signal injection circuit activates an internal error amplifier which reduces the output voltage. Conversely, if the output voltage falls below the reference voltage, the error amplifier increases the output voltage. The error amplifier is continuously active and ensures that the output voltage is regulated within specifications.
The IRU3037CSTRPBF is designed to provide excellent load regulation, fast load transient response and load disconnect feature with very low system noise. This switching controller is also designed to provide an output voltage with or without synchronization to PFC controllers. It is a highly integrated device that offers advanced features such as programmable switching frequency, programmable output voltage, cycle-by-cycle current limit protection and an integrated bootstrap diode. It is an ideal solution for applications such as industrial and telecom power supplies, severs, datacom, automotive applications, and LED drivers.
