AS3729B-BWLT

AS3729B-BWLT is a specialized power management integrated circuit (PMIC) which provides highly efficient regulation of power supplies supplied to application processor cores, as well as other power-critical components, in consumer and industrial applications. PMICs provide system-level power and enable the efficient operation of a wide array of power sensitive components by regulating and controlling low-voltage and low-power signals. The AS3729B-BWLT provides a highly efficient power management solution, providing both linear and switching regulation solutions to provide highly efficient and damage-resistant power supplies in a small footprint.

The AS3729B-BWLT includes an integrated high-performance switch-mode power supply, a programmable current-limit protection circuit and an adjustable output voltage regulator. It operates over an extended temperature range (+40°C to +85°C), is packaged in a 3x3mm 20-leaded QFN-package, and can be used in a variety of Power Management applications.

The AS3729B-BWLT’s integrated high-performance switch-mode power supply delivers up to 5A on each output (3-3.3V) with very low ripple and noise, which is key for many advanced microprocessor applications. The integrated current-limit protection circuit ensures the system is not overloaded, while the adjustable output voltage regulator can be used to ensure the system has the right voltage levels. Finally, the AS3729B-BWLT is capable of operating over an extended temperature range, allowing high-reliability solutions.

When designing with the AS3729B-BWLT, engineers should incorporate the PMIC into an overall system power management strategy. In particular, engineers should ensure the system-level power-on reset (POR), logic power-on reset (LOR), power-good indicator (PGI) and power good controller (PGC) are correctly integrated and used to indicate (and control) when the power supply is functioning correctly. Additionally, as the outputs are switch-mode regulated, it is important to pay attention to the power delivery path of the integrated circuit and choose a suitable package.

The AS3729B-BWLT PMIC is most commonly used in applications such as digital cameras, display devices, and other consumer and industrial applications where a low-power, high-efficiency power management solution is needed. This integrated circuit is also useful in applications where a wide temperature range is required (such as automotive electronics), or in systems that require a longer battery life.

The AS3729B-BWLT provides an efficient and reliable power management solution for many applications. By incorporating the integrated high-performance switch-mode power supply, programmable current-limit protection circuit and adjustable output voltage regulator into a system design, engineers can reduce board size, reduce power losses and improve overall system reliability.

In summary, the AS3729B-BWLT is a specialized PMIC designed for specific applications requiring efficient and reliable power management solutions. By integrating a high-performance switch-mode power supply, a programmable current-limit protection circuit and an adjustable output voltage regulator, the AS3729B-BWLT provides an effective power management solution in a small package.
