AS3712-BQFP-00 Application Field and Working Principle

AS3712-BQFP-00, or Advanced Switching Regulator, is an advanced step down power management integrated circuit (PMIC), designed specifically for low power applications with limited space. This advanced PMIC is a highly integrated, multi-functional device that offers a complete power solution for electronic designs that require advanced power supply without external passives.

The AS3712-BQFP-00 is designed for applications such as smartphones and tablets, where power consumption and component density are critical. The device is ideal for applications where size and performance are both important. It provides an integrated solution for sophisticated, low power applications that require high performance and efficient power supply.

Applications of AS3712-BQFP-00

The AS3712-BQFP-00 offers high efficiency and low power consumption in multiple power supply architectures, as well as an integrated system design platform. The high-efficiency can be enhanced with dynamic frequency scaling, allowing it to adjust its switching frequency based on the input voltage. The device also offers current-limit protection and variable output voltage control.

The AS3712-BQFP-00 is suitable for use in power sensitive applications such as LCD TV, gaming consoles, Blu-ray players, point-of-sale terminals, vending machines and security systems. It is also well-suited for use in other low power applications such as solar power monitoring and street lamps.

Working Principle of AS3712-BQFP-00

The AS3712-BQFP-00 is based on advanced micro-controller technology. It uses an oscillator to generate a 4MHz switching frequency, and then combines the current sense / control circuitry to regulate the output voltage. The current-sense / control circuit senses the voltage across a resistor and adjusts the switching frequency accordingly, to maintain the output voltage within the specified limits.

The AS3712-BQFP-00 has a number of built-in features such as a power-on reset circuit, short-circuit protection, and over-temperature protection. These features, combined with adjustable UVLO, transient protection, and over current protection, provide a robust and reliable power management solution.

In addition to these features, the AS3712-BQFP-00 also offers a standby function, allowing it to save energy when not in use. This standby function can be implemented using the enable input, which can be used to enable or disable the device. The device also supports a burst mode operation, which enables it to operate in low power mode while still meeting the required performance level.

Conclusion

The AS3712-BQFP-00 is an advanced power management integrated circuit, designed specifically for low power applications with limited space. It provides an integrated solution for sophisticated, low power applications that require high performance and efficient power supply. The device offers high efficiency and low power consumption in multiple power supply architectures and features current-limit protection, over current protection, and adjustable UVLO, as well as a standby function. This makes it ideal for use in power sensitive applications such as LCD TV, gaming consoles, and point of sale terminals, as well as other low power applications such as solar power monitoring and street lamps.
