Power Management Integrated Circuit (PMIC) is a type of integrated circuit designed to manage power and energy requirements of a system. It is a collection of circuits that can be used to monitor and control the amount of power consumed and generated by the system. PMIC is used in various applications such as mobile devices and automotive systems. The AL1692-30BAS7-13 is a PMIC dedicated to LED driving applications. It is ideal for large scale LED lighting systems as it supports up to 40 channels of output.

Applications of AL1692-30BAS7-13

The AL1692-30BAS7-13 is a highly integrated PMIC integrated circuit. It has a wide range of uses, such as general-purpose LED driver, architectural lighting and outdoor lighting. The IC combines a buck converter, programmable current sink, linear regulator and switch in a small package. It is designed to drive high-end LEDs in up to 40 channels with low-side drivers, up to 20 channels with high-side drivers, or up to 10 channels with bidirectional drivers.

The AL1692-30BAS7-13 is also well suited for mobile applications as it can be used to drive a maximum of 4 displays. It features a programmable PWM signal generator for up to 16 channels for driving a variety of display backlights. Furthermore, it provides a range of protection functions such Interface Short, Over Temperature, Over Voltage, Under Voltage and Over Current protection.

Working Principle of AL1692-30BAS7-13

The AL1692-30BAS7-13 PMIC works in either buck or boost mode. It can operate in both modes simultaneously, depending on the output voltage and current requirements. In buck mode, the AL1692-30BAS7-13 can step down the input voltage to the desired output voltage. On the other hand, in boost mode, it steps up the input voltage to the desired output voltage. The device can support power levels up to 5A and voltage levels from 1V to 5V.

When the AL1692-30BAS7-13 is used in buck mode, it acts like a switching regulator. The switching frequency of the PMIC is adjustable and has a range of 500kHz to 1.2MHz. The device can generate a PWM signal with a frequency of up to 1MHz. When it is used in boost mode, the switching frequency of the device is fixed at 1MHz.

In addition, the device also has a programmable current sink and linear regulator which can be used to regulate the current and voltage in the output. The programmable current sink can be used to sink a maximum of 5A of current and the linear regulator can be used to regulate the output voltage from 1V to 5V.

Conclusion

The AL1692-30BAS7-13 is a PMIC designed for LED driving applications. It integrates a buck converter, programmable current sink, and linear regulator into a small package. It can be used for general-purpose LED drivers, architectural lighting, outdoor lighting, and mobile displays. It has a switching frequency range of 500kHz to 1.2MHz and can drive up to 40 channels of output in buck mode. Additionally, it includes programmable current sink, linear regulator, and protection functions for safety and reliability.
