IRU1010-33CD

The IRU1010-33CD is a linear voltage regulator, specifically a Buck and Boost Synchronous DC-DC Converter, that is part of the PMIC (Power Management Integrated Circuit) family. It is designed to provide a cost-effective solution to a wide variety of applications, including computing, gaming and networking. The device is designed to be used in environments where both input voltage and output current are required to be controlled in order to maintain a stable output voltage.

The IRU1010-33CD is capable of boosting or bucking an input voltage to provide a regulated output voltage with high accuracy, efficiency (up to 95%), high power density and low noise. The device has a wide input voltage range, from 6V to 36V, and is able to adjust output voltage from 0.8V to 33V. It also has low power consumption, making it ideal for battery-powered applications.

The IRU1010-33CD is built with internal power MOSFETs and features low reverse current below 2nA. It is also capable of handling high inrush current up to 2.5A in boost mode and 6A in buck mode, making it suitable for applications that require high current-handling capabilities. It also has protection features, including over-temperature, under-voltage and short circuit protections, ensuring the device works reliably and safely.

When it comes to the working principle of the IRU1010-33CD, the device operates in buck and boost modes by controlling an internal MOSFET switch in order to maintain a stable output voltage. In buck mode, the internal MOSFET switch continuously discharges the output capacitor and reduces the output voltage with the difference between input voltage and the internal reference voltage, resulting in a lower output voltage compared to the input. In boost mode, the MOSFET switch is not connected during steady state, allowing the output voltage to be slightly higher than the input voltage.

In summary, the IRU1010-33CD is a linear voltage regulator from the PMIC family that provides an efficient and cost-effective solution for applications requiring a wide input voltage range and high current-handling capabilities. It offers a wide range of features, including protection features and high power density. Additionally, it is capable of regulating input voltage in both buck and boost modes by controlling an internal MOSFET switch.
