TI has low power converter for energy harvesting designs
The industry's lowest power dc/dc step down converter has been touted by Texas Instruments.
The TPS62736 is designed to increase the amount of harvested energy an end application can use by up to 70%.
Target applications include wireless sensor networks, monitoring systems, wearable medical devices, smoke alarms and mobile accessories.
"This new power circuit gives designers capabilities not possible with traditional battery powered systems," said Sami Kiriaki, senior vice president of TI's Power Management group.
The converter is designed to deliver high power conversion efficiency from 10 to 50mA output currents, and consume only 350nA of active current and 20nA during standby.
It is optimised to achieve greater than 90% efficiency across output currents higher than 15uA.
The regulator steps down the voltage from a power source, such as a thin film or regular battery or a super capacitor and features a programmable output voltage.
