Conclusion

The trend toward lower currents is clear. The need to achieve high efficiency at no- or light-load conditions requires power solutions to tightly regulate the output while maintaining ultra-low supply current. With TI’s portfolio of ultra-low IQ technologies and products, you can maximize your battery run time and enable low power consumption in your next design.

The key benefits of TI technologies for low IQ include:

  • Low, always-on power — long battery run times, enabled by ultra-low leakage process technologies and novel control topologies.
  • Fast response times — fast wake-up comparators and zero-IQ feedback control enable fast dynamic responses without compromising low power consumption.
  • Reduced form factors — area reduction techniques for resistors and capacitors facilitate integration into space-constrained applications while not affecting quiescent power
