AS3711-BWLT-00 Application Field and Working Principle

The AS3711-BWLT-00 is part of the AS3711 family of Power management integrated circuits (PMICs) specializing in Wide Load Transient (WLT) and body biasing for mobile processors applications. This PMIC can provide all necessary power rails for a mobile processor system, both in Off and DRAM self-refresh and providing advanced power sequencing. In addition to the main regulators, the AS3711 family supports additional auxiliary power rails, such as DDR, BT and analog VDD. The As3711-BWLT-00 also supports multiple loads in order to optimize design and power bill of materials. The AS3711-BWLT-00 will allow mobile processor designs to be optimized for power consumption and performance.

The AS3711-BWLT-00 is the industry\'s first WLT dedicated PMIC offering a robust device layout and cost-optimized design. WLT technology is a method of controlling load currents and voltage ripple to eliminate noise from the system and minimize power consumption. WLT is also capable of boosting power supply rail voltage margins to support higher core/IO voltages. As3711-BWLT-00 provides very precise current control by using unique digital power control algorithms. The algorithms can respond to up to 1000 μs of load transient response making AS3711-BWLT-00 ideal for multi-core processors.

The AS3711-BWLT-00 is equipped with an enhanced body-biasing module. Body biasing is a power optimization technology developed to increase the performance and reduce the power consumption of applications processors. This technology works by tuning the voltage and current of the core to enable power savings and boost performance. The AS3711-BWLT-00 body biasing module is capable of controlling 8 core systems and also supports high-frequency switching and low-frequency buck and boost voltage changes.

The AS3711-BWLT-00 is a versatile power management IC with multiple options for power sequencing. It lets you control up to seven supply rails and their associated load currents through one chip. The device also supports On-The-Fly (OTF) Over Voltage protection (OVP) for all its supply rails, allowing for enhanced supply protection.

The AS3711-BWLT-00 includes a Sequencer Module which offers a wide range of programmable power sequencing options. It allows you to control the order in which power is sequenced to the various load rails, as well as how long each state remains active. The sequencer module also enables the use of soft shut-down and over-voltage protection. Another key feature is the ability to dynamically set user-defined levels for each supply rail ensuring that the system functions properly during extreme conditions.

The AS3711-BWLT-00 is an ideal device for power optimization in high-end mobile processors. It offers a high degree of integration and flexibility with features such as robust WLT, body biasing and programmable power sequencing. The AS3711-BWLT-00 enables mobile processor designs to meet demanding performance, power, and reliability requirements. By providing both cost and design flexibility, it has the capability to reduce total system cost.
