Ultra-low PMICs aim to enable next wave of energy harvesting design
Texas Instruments has introduced five new next-generation power management integrated circuits that efficiently acquire and manage microwatts to milliwatts  of power harvested from light, heat or mechanical energy sources.
temporarily.

For lower current designs, TI’s new TPS62737 converter for 200-mA designs and TPS62736 for 50-mA designs provide an ultra-low 370 nA quiescent current during active operation and 15 nA during sleep, while achieving 90 percent efficiency at output currents lower than 15 uA.

Availability and Pricing

All products are shipping in volume production and are available through TI’s worldwide distributor network. The bq25570 and bq25505 come in a 3.5-mm by 3.5-mm QFN package, and are priced at $3.20 and $2.40, respectively, in 1,000-unit quantities. The TPS62740 comes in a tiny 2-mm by 3-mm SON package, and is priced at $1.10 in 1,000-unit quantities. The TPS62737 and TPS62736 are available in a 3.5-mm by 3.5-mm QFN package, and are priced at $1.00 and $0.80, respectively, in 1,000-unit quantities.
