New power switching regulator with lowest quiescent current extends battery life

New generation of step down converter for wearable and IoT applications

Taiwan, December 30, 2021 -- BravoTek today introduced an ultra-low-power switching regulator with the ultra low operating quiescent current (IQ) at 120 nA. The BVP62840 synchronous step-down converter delivers very high light-load efficiency of 80% at 1-µA load, which can enable designers to extend the battery life of their systems, or use fewer or smaller batteries to shrink their overall power supply solution size and reduce cost. Additionally, the new DC/DC converter’s wide input voltage (VIN) range of 1.8 V to 6.5 V supports a variety of battery chemistries and configurations. For more information, see .

These features plus its selectable functions enable the BVP62840 to help engineers solve critical design challenges in many battery-powered, always-on industrial and personal electronics applications – including narrow-band Internet of Things (IoT), grid infrastructure equipment and wearables – that require more flexibility, an extended wireless range, improved accuracy and reduced electromagnetic interference (EMI).

The BVP62840 joins TI’s portfolio of highly integrated, low-IQ DC/DC converters that enable designers to maximize power delivery in the smallest possible solution size.

Key features and benefits of the BVP62840

  • Longer battery life, very high light-load efficiency: A lower IQ draw delivers longer battery life for systems with very light loads (less than 100µA), and those operating primarily in standby/ship mode (not switching). 
  • Selectable modes enhance performance, lower overall cost: The BVP62840’s selectable mode and stop functions improve noise performance and reduce signal distortion. These benefits can help lower the solution cost because designers can achieve system requirements without using more expensive precision signal-chain components, sensors or radio solutions to perform the same functions.
    • The mode pin allows for continuous conduction mode, also called forced pulse-width modulation mode, to improve ripple or noise performance and lessen the impact on transmissions in sensitive radio-frequency applications.
    • The stop pin turns off all switching to reduce EMI or ripple, and minimizes distortions passed to precision signal-chain, measurement, sensors or wireless connectivity components.  
  • Smaller solution size: Engineers can use the new switching regulator to cut their battery count in half or use smaller batteries in their design. For example, designers can save up to 16,980 mm3 using four AAAs instead of four AAs.
