Innovative wide Vin DC/DC controller features industry's highest 65-V operation

2.2-MHz, low-quiescent-current buck converter significantly reduces system noise and saves space in sensitive automotive power-supply systems

LONG BEACH, Calif., March 21, 2016 — (PRNewswire) —  APEC -- Texas Instruments (TI) (NASDAQ: TXN) today introduced a 2.2-MHz, dual-channel synchronous buck converter with a unique set of features designed to significantly reduce electromagnetic interference (EMI) and high-frequency noise in high-voltage DC/DC step-down applications such as automotive infotainment and high-end cluster power-supply systems. The LM5140-Q1 controller includes dual outputs with phase interleaving and is offered in wettable flank packaging that speeds manufacturing. Together with TI's WEBENCH® Automotive Design tool, the LM5140-Q1 enables engineers to get their automotive designs to market faster. For more information, samples and an evaluation module, see www.ti.com/lm5140q1-pr.

TI's innovative LM5140-Q1 wide Vin DC/DC controller features the industry's highest 65-V operation, significantly reduces system noise, and saves space in sensitive automotive power-supply systems.

LM5140-Q1 key features and benefits:

For industrial applications requiring a regulated voltage above 15 V such as programmable logic controllers or factory automation equipment, read the blog post, " How to extend a controller's output-voltage range."

The LM5140-Q1 joins the recently released LM53600-Q1, LM53601-Q1, LM53602-Q1 and LM53603-Q1 buck converters to create a complete family of controllers and converters designed for automotive systems that draw from less than 1 A of power to more than 10 A. All of these devices feature greater than 2-MHz switching frequency, low operating IQ and EMI reduction features.

The LM5140-Q1 uses external metal-oxide semiconductor field-effect transistors (MOSFETs) to support up to 10-A dual-channel loads for high-end infotainment systems and other noise-sensitive systems. The LM53600-Q1 and LM53601-Q1 support 650-mA and 1-A load current, respectively, for emerging advanced driver assistance (ADAS) systems. The LM53602-Q1 and LM53603-Q1 deliver 2-A and 3-A loads, respectively, for higher-current ADAS and infotainment systems.
