Introduction

AS3608A-BQFP-00 is an advanced power management integrated circuit (PMIC) that combines multiple power management functions and features in a single chip. This PMIC was designed as an efficient, singular solution for embedded applications. It provides multiple regulators, flexible power switch control, hardware-level protection, and LED brightness control.

Application Field

The AS3608A-BQFP-00 is a perfect power management solution for small, low-power embedded systems. It specifically targets products that require low power management but have more stringent requirements. For instance, modern smart-home products require reliable power management, and the AS3608A-BQFP-00 is the perfect solution for this specific use case. The AS3608A-BQFP-00 can provide flexibility, reliability, and integration for industrial, automotive and other applications, including power-sensitive wireless systems, such as those used in smart homes.

Working Principle

The AS3608A-BQFP-00 implements a switched mode power supply (SMPS) using a two phase pulse width modulation (PWM) control loop. In this topology, the two phases are 180 degrees phase shifted with respect to each other. When the output voltage needs to be increased or decreased, the duty cycle of the two phase PWM signals are adjusted accordingly to maintain the desired output voltage of the SMPS. The AS3608A-BQFP-00 includes a host of protection features such as input over-voltage protection, output under voltage protection, output short-circuit protection, thermal-protection, and over-current protection. These features provide a high-performance, low-cost solution for data-sensitive applications, such as small embedded systems.The AS3608A-BQFP-00 chip also includes several voltage regulators to provide precise voltage outputs at different levels. These regulators help to provide power to different parts of the IC.In addition, the AS3608A-BQFP-00 provides precision LED dimming control so that LED lighting can be tailored to the specific needs of the application.

Conclusion

The AS3608A-BQFP-00 is an advanced PMIC designed for high-performance and cost-effective solutions for embedded systems. By combining multiple power management features on a single chip, the AS3608A-BQFP-00 is an ideal solution for industrial, automotive and other applications, including power-sensitive wireless systems. It helps to provide flexibility, reliability, and integration where necessary, while keeping the cost of implementation low. The combination of its SMPS topology, protection features, voltage regulators, and LED dimming capabilities makes the AS3608A-BQFP-00 an ideal solution for smart home products.
