Texas Instruments has introduced what it claims the industryís lowest power DC/DC step-down converter, an 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.
TIís TPS62736 DC/DC converter delivers 10 uA to 50 mA output currents, and consumes 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.
The TPS62736 is currently sampling through TI. It comes in a 3.5-mm by 3.5-mm QFN package and is priced at US$2.00 in 1,000-unit quantities. Volume production is expected later in the first quarter. Evaluation modules are available to select customers
