The TPS65023x device is an integrated power management IC for applications powered by one
Li-Ion or Li-Polymer cell, which require multiple power rails. The TPS65023x provides three highly efficient, step-down converters targeted at providing the core voltage, peripheral, I/O, and memory rails in a processor-based system. The core converter allows for on-the-fly voltage changes through serial interface, allowing the system to implement dynamic power savings. All three step-down converters enter a low-power mode at light load for maximum efficiency across the widest possible range of load currents.

The TPS65023x also integrates two general-purpose 200-mA LDO voltage regulators, which are enabled with an external input pin. Each LDO operates with an input voltage range from 1.5 V to 6.5 V, thus allowing them to be supplied from one of the step-down converters or directly from the battery. The default output voltage of the LDOs can be digitally set to 4 different voltage combinations using the DEFLDO1 and DEFLDO2 pins. The serial interface can be used for dynamic voltage scaling, masking interrupts, or for disabling or enabling and setting the LDO output voltages. The interface is compatible with both the fast and standard mode I2C specifications, allowing transfers at up to 400 kHz. The TPS65023x is available in a 40-pin WQFN package, and operates over a free-air temperature of –40°C to 85°C.

TIDA-01589 — 具備雜訊消除與回波抵銷功能的高保真、近場雙向音訊參考設計

人機互動需要聲學介面,以提供全雙工免手持通訊。在免手持模式下,來自喇叭的部分遠端或近端音訊訊號會耦合至麥克風。此外,在雜訊環境中,除了可擷取有用的近端音訊訊號外,麥克風還會擷取環境雜訊。擷取的多麥克風音訊訊號會受到聲學背景雜訊及回波訊號破壞,這些訊號會大幅降低所需訊號的清晰度,並限制後續音訊處理系統的性能。此參考設計展示了雙麥克風,其用於透過立體聲 ADC 實現音訊輸入,透過低功耗 DSP 執行雜訊降低、聲音回波消除和其他音訊品質強化演算法。此設計還採用了 TI 智慧型放大器技術,可透過微型喇叭實現高品質、高 SPL 音訊輸出。
