Description : Ultra Low Power Boost Converter With Battery Management for Energy Harvester Applications View

General Description
The bq25504 is the first of a new family of intelligent integrated Energy harvesting Nano-Power Management solutions that are well suited for meeting the special needs of Ultra low power Applications. The product is specifically designed to efficiently acquire and manage the microwatts (µW) to miliwatts (mW) of power generated from a variety of DC sources like photovoltaic (solar) or thermal electric generators. The bq25504 is the first device of its kind to implement a highly efficient Boost Converter/charger targeted toward products and systems, such as wireless sensor networks (WSN) which have stringent power and operational demands. The design of the bq25504 starts With a DC-DC Boost Converter/charger that requires only microwatts of power to begin operating. Once started, the Boost Converter/charger can effectively extract power from low voltage output Harvesters such as thermoelectric generators (TEGs) or single / dual cell solar panels. The Boost Converter can be started With VIN as low as 330 mV typ., and once started, can continue to harvest Energy down to VIN ≃ 100 mV.

Description : 2-W Constant Output Power Class-D Audio Amplifier With Adaptive Boost Converter and Battery Tracking Speakerguard™ AGC View

3 Description
The TPA2015D1 is a high efficiency Class-D audio power amplifier With Battery-tracking SpeakerGuard™ AGC technology and an integrated adaptive Boost Converter that enhances efficiency at low output power. It drives up to 2 W into an 8 Ω speaker (6% THD). With 85% typical efficiency, the TPA2015D1 helps extend Battery life when playing audio.
