Ultra-Low Power Converter

Texas Instruments Incorporated introduces the industry’s lowest power DC/DC step-down converter, which increases the amount of harvested energy an end application can use as much as 70 percent over alternative devices. The ultra-low power circuit enables battery-free power to applications, such as wireless sensor networks, monitoring systems, smoke detectors, wearable medical devices and mobile accessories.   “Imagine not having to change the battery in your smoke detector – ever,” said Sami Kiriaki, senior vice president of TI’s Power Management. “TI continues to develop circuits with very low operating current and high power efficiency that can manage microwatts to milliwatts and extract ambient energy. This new power circuit gives designers capabilities not possible with traditional battery-powered systems.”   

TI’s TPS62736 DC/DC converter delivers high power conversion efficiency from 10 uA to 50 mA output currents, and consumes only 350 nA of active current and 20 nA during standby. The converter achieves greater than 90-percent efficiency across output currents higher than 15 uA. The TPS62736 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.
