Texas Instruments (TI) announced that it has achieved extended battery life and cost reductions by using a new DC/DC converter to achieve low quiescent current (IQ).

On the 3rd, TI held an online press conference under the theme "Maintaining Low IQ in Next-Generation Industrial and Automotive Applications" and announced the release of a bidirectional buck/boost converter with an extremely low IQ of 60nA.

Troy Coleman, Vice President who gave a presentation at the event, presented five challenges in power management: low EMI, power density, low IQ, low noise and accuracy, and isolation. He stated that given the rapidly increasing global battery usage, it is important to extend battery life and product life without compromising system performance by using low quiescent current (IQ) technology.

In addition, considering that standby mode accounts for a significant portion of battery usage patterns, a power solvent that maintains extremely low current while strictly managing power output is required to achieve high battery efficiency in standby mode.He mentioned that a solution was needed.

To this end, TI introduced that it is striving to achieve ultra-low IQ by reducing form factor size, low always-on power consumption, and fast response times.

Accordingly, it was announced that the TPS61094 buck/boost converter, LMR43620/Q1 and LMR43610/Q1 buck converters, and the LM7472X-Q1 ideal diode family were recently released as the industry's lowest IQ devices.

It was noted that the TPS61094 integrates supercapacitor charging capabilities to maintain the industry's lowest IQ, excelling in peak load and backup power management for battery-powered industrial applications such as smart meters. Additionally, it was stated that the integrated buck/booster converter simplifies the design and extends battery life through high output current and low IQ.

In particular, it was mentioned that the battery life of applications requiring operation for more than 10 years on a single battery has been extended by up to 20% with a low IQ of 60nA, and with an inductor current limit of 2A, it provides twice the output current compared to competing boost converters, while reducing the number of components by 50% and saving board space.

It was announced that the LMR43620 and LMR43620-Q1 are the industry's first buck converters operating with a wide V-IN, operating with an IQ of less than 3µA at 150°C T-jmax, and providing pin-to-pin compatible 1A devices (LMR43610/Q1) in a low EMI HotRod™ package of 2mm x 2mm. It was also stated that the design is suitable for industrial and automotive applications in harsh environments.

It was mentioned that the LM74720 Q1 family features the lowest power consumption always-on system design through automotive and low IQ ideal diode family, and enables fast execution and shutdown for reverse battery protection. They also stated that they reduced the size of the solution while maintaining the system's protection functions.

“With these TI product families, engineers can meet requirements in automotive applications more efficiently and in power-constrained environments, and ensure the highest level of system protection with high-speed on/off technology,” explained Vice President Troy Coleman.
