The IRU1010CSTR is a Linear Voltage Regulations (LVR) PMIC. It helps to maintain a consistent voltage supply within a specified range in the device, while providing current regulation and ramp-up and ramp-down capabilities.

Design engineers specify the target output voltage on the device. It then maintains that stable voltage regardless of input voltage fluctuations and load changes, up to a pre-set current limit. It does this through actively adapting its source and drain current to regulate the output voltage, as well as its slew rate for eliminating response times.

When compared to other PMICs, the IRU1010CSTR has the unique ability to provide wide bandwidth current regulation, allowing for greater accuracy and efficiency when it detects changes in current, which is ideal for a variety of applications.

Applications

Given its features and capabilities, the IRU1010CSTR is particularly suitable as a form of voltage regulator and current limiter in a variety of industrial applications, including power management systems, automotive, telecommunications and audio/visual applications. Because its wide bandwidth current regulation function allows for greater accuracy in voltage regulation, this PMIC can come in handy where precision is needed.

In the automotive industry, the IRU1010CSTR can be used to regulate the current and voltage supply needed to maintain or increase the performance of parts such as electric seats, sun roofs, headlights, tail lights, etc. In the power management industry, it can be used to precisely and reliably regulate voltage outputs for a range of devices, from motors and generators to batteries and switchgear.

The telecommunications industry is yet another area of focus for the IRU1010CSTR, particularly where high accuracy is needed. The PMIC can be used for power management solutions for broadband systems and cellular base stations, ensuring reliability, performance and improved efficiency.

Working Principle

The IRU1010CSTR’s primary feature is the current regulation technique it employs to maintain the output voltage of a device within a pre-determined range. Known as ‘Tracking Current Limiting’, it works by actively adapting the voltage source or drain current to regulate the output voltage.

The operating principle is simple: when the output voltage rises or drops, the PMIC senses this change and initiates a slow, gradual change in the voltage source or drain current. This in turn helps to re-establish the targeted voltage level. It is this tracking current limiting functionality that allows the IRU1010CSTR to provide a high degree of accuracy and precision in voltage regulation.

To further enhance the PMIC’s accuracy, the IRU1010CSTRalso employs a slew rate for ramp-up and ramp-down times for its voltage source/drain current behavior. All these functions work together to help provide a stable, reliable power supply even when input voltage fluctuations and load changes occur.

Conclusion

The IRU1010CSTR LVR PMIC is designed to provide a high level of precision and accuracy when it comes to voltage regulation. With its tracking current limiting and slew rate functions, it is an excellent choice for a variety of applications, from automotive and power management to telecommunications and audio/visual systems.
