Industry's first multiphase bidirectional current controller from TI


DALLAS, March 20, 2017 /PRNewswire/ -- Texas Instruments (TI) (NASDAQ: TXN) today introduced the industry's first fully integrated multiphase bidirectional DC/DC current controller, which efficiently transfers electric power greater than 500 W per phase between dual 48-V and 12-V automotive battery systems. The highly integrated LM5170-Q1 analog controller features an innovative average current-mode control method that overcomes the challenges of today's high-component-count, full digital control schemes. For more information, samples and an evaluation module, see www.ti.com/lm5170q1-pr.

TI will demonstrate the LM5170-Q1 controller in booth No. 701 at the Applied Power Electronics Conference (APEC) in Tampa, Florida, March 27-29, 2017. The LM5170-Q1 is the latest in TI's portfolio of industry-leading DC/DC converters, controllers and charge pumps, enabling engineers to innovate and differentiate their power supply designs.

Hybrid electric vehicles use both a high-voltage 48-V battery and the standard 12-V automotive battery. Design engineers typically manage these dual battery systems using a digital control scheme, which includes multiple discrete components such as current-sense amplifiers, gate drivers and protection circuits. These full digital control schemes are bulky and expensive. To solve this challenge while improving performance and system reliability, TI offers a mixed architecture in which the microcontroller handles higher-level intelligent management, and the highly integrated LM5170-Q1 analog controller provides the power conversion. Read the blog post, "Interconnecting automotive 48V and 12V rails in dual battery systems," to learn how to overcome the challenges of designing a power supply for hybrid electric vehicles.

LM5170-Q1 key features and benefits

Availability, packaging and pricing
Available in volume now through the TI store and authorized distributors, the LM5170-Q1 is offered in a 48-pin, 9-mm by 9-mm quad flat package (QFP) and priced at US$5.84 in 1,000-unit quantities. Order the LM5170EVM-BIDIR evaluation module, and download the PSpice transient model and LM5170-Q1 quick-start DC/DC synchronous buck converter design tool.
