Wide-VIN DC/DC buck regulators simplify design of industrial power supplies
Texas Instruments introduced two wide-VIN synchronous SIMPLE SWITCHER DC/DC buck regulators in ultra-small HotRod quad flat no-lead (QFN) packaging. The highly integrated 3-A LMR33630 and 2-A LMR33620 step-down voltage converters feature the industry’s best full load efficiency – 92 percent – for rugged and reliable industrial power supplies with switching frequencies up to 2.1 MHz. Used in conjunction with TI’s WEBENCH Power Designer, the converters […]
Three new Class-D amplifiers solve smart-home audio design challenges
Texas Instruments introduced three new digital-input Class-D amplifiers that enable engineers to deliver high-resolution audio in more smart-home and voice-enabled applications. By combining first-of-its-kind integration, real-time protection and new modulation schemes, TI’s new audio devices allow designers to reduce board space and overall bill of material (BOM) cost. These new amplifiers are designed for personal […]
Step-down power module works at 5.5 V, delivers 6 A with 95% efficiency
Texas Instruments (TI) today introduced a 5.5-V step-down power module that delivers true, continuous 6-A output current with up to 95 percent efficiency. The easy-to-use TPSM82480 DC/DC module integrates power metal-oxide semiconductor field-effect transistors (MOSFETs) and shielded inductors into a tiny, low-profile footprint for space- and height-constrained applications such as point-of-load telecommunications, networking, and test and measurement […]
DC power rails, Part 2: Single-rail and multi-rail management
Part 1 of this FAQ discussed development and designation of basic DC power rails. Part 2 looks at key specifications of these rails, and management of single- and multi-rail systems. Q: What’s an important point to remember whenever discussing voltage? A: The tendency is to say “this voltage rail is at such-and-such voltage” or “the […]
Wide-VIN synchronous DC/DC buck regulators generate little EMI
Texas Instruments introduced two families of wide-VIN synchronous DC/DC buck regulators with industry-leading electromagnetic interference (EMI) and thermal performance. The highly integrated 5-A and 6-A LM73605/6 and 2.5-A and 3.5-A LM76002/3 step-down voltage converters feature an optimized pinout and best-in-class thermal coefficient to simplify the process of achieving EMI compliance and higher reliability for rugged industrial and […]
Compact step-down converters offer 5 and 3-V outputs
Texas Instruments introduced two new 4-V to 36-V power modules that measure just 3.0 mm by 3.8 mm and require only two external components for operation. The 0.5-A LMZM23600 and 1-A LMZM23601 DC/DC step-down converters achieve up to 92 percent efficiency, which minimizes energy loss, and feature tiny MicroSiP packaging that shrinks board space by […]
Three-channel automotive LED controller uses external MOSFET for better thermal dissipation
Texas Instruments introduced the first 3-channel high-side linear automotive light-emitting diode (LED) controller without internal MOSFETs which gives designers greater flexibility for their lighting designs. The TPS92830-Q1’s novel architecture enables higher power and better thermal dissipation than conventional LED controllers, and are particularly beneficial for automotive LED lighting applications that require high performance and reliability.
