PMIC (Power Management IC) refers to an integrated circuit which manages the power supply for any system, either for power supply or for power management functions. Specialized PMICs, such as the BQ51013BYFPT, are specifically designed to have a wide range of applications and offers extensive features with low leakage and standby current.

The BQ51013BYFPT is a 5.10 V synchronous buck converter PMIC which has a 4.2 to 5.5 V operating voltage. It has a wide selection of operating temperature range, from -40°C to 85°C, making it suitable for use in a number of industrial applications. It features soft start, cycle-by-cycle current limit and over temperature protection to help ensure maximum system reliability.

Application Field

The BQ51013BYFPT is specifically designed for portable devices, including but not limited to phones, tablets, and digital cameras. It works well as a power supply for LCDs as well as for a variety of applications such as automotive, consumer, and industrial plans. Portable devices are increasingly becoming more complex, complete with processors and other components. As such, it is important to ensure that a reliable power supply is available for the device’s voltage regulation. This is where the BQ51013BYFPT comes in.

Working Principle

The BQ51013BYFPT is a synchronous buck converter, which means that it converts one voltage level to another using a power switch. It works in synchronization with the incoming voltage level to provide a precise output. At the heart of the BQ51013BYFPT is the voltage converter which is designed to convert an input voltage to a precise output voltage. The voltage converter gets its instructions from the integrated MCU (microcontroller unit) which is connected to an external component, typically an inductor.

The inductor is responsible for storing energy and releasing it to the output of the buck converter. The energy stored is proportional to the current flow which is determined by the inductor’s inductance. As the inductor’s current flow changes, the MCU makes adjustments in order to maintain a stabilized output voltage.

The BQ51013BYFPT also features an adaptive current sensing mechanism which further increases the device’s precision and stability. This feature allows the device to compensate for overshoots in the output voltage to ensure that a stable output voltage is maintained.

Conclusion

The BQ51013BYFPT is a powerful, highly efficient and reliable synchronous buck converter PMIC that is designed specifically for a wide range of applications. Its wide operating temperature range, low leakage currents, and over temperature protection features make it perfect for portable device applications. Its adaptive current sensing mechanism ensures that the output voltage is always maintained within the correct range.
