TI introduces integrated triple-output synchronous buck converters

DALLAS (July 31, 2014) – Texas Instruments (TI) (NASDAQ: TXN) today introduced the next generation of its integrated triple-output synchronous step-down switching regulators with smaller footprint and higher efficiency. The TPS65261 and TPS65262 DC/DC converters feature small QFN packages and up to 96 percent efficiency for such applications as digital television, set-top boxes, home gateway and access point networks, wireless routers, point-of-sale machines, and surveillance equipment. For more information, samples and an evaluation module, visit www.ti.com/tps65261-pr andwww.ti.com/tps65262-pr.

The new family of DC/DC converters joins TI’s family of multi-channel synchronous buck converters that include the TPS65250 and the TPS65251developed for set-top box applications.  Read a blog on the topic, “Multi-channel DC/DC (POL) solutions for audio/visual systems.”

TPS65261 and TPS65262 key features and benefits

  • Wide 4.5-V to 18-V input supply voltage range for intermediate bus voltages operating off 5-V, 9-V, 12-V or 15-V power buses or batteries.

  • Constant frequency peak current mode simplifies design and enables system optimization.

  • 5-mm by 5-mm by 0.9-mm QFN package is 44 percent smaller than previous generation.

  • 0.6-V feedback reference supports processors demanding lower output voltage.

  • Integrated automatic power up/down sequencing offers easy power control.

  • The TPS65261 provides 82 percent light load efficiency at 10 mA and offers three outputs of rated current at 3A/2A/2A. It features an adjustable 250-kHz to 2-MHz switching frequency with pulse skipping.  For forced continuous current operation without pulse skipping, TI offers theTPS65261-1.

  • The TPS65262 provides fixed 600-kHz switching operation and offers three outputs of rated current at 3A/1A/1A. Two integrated 200-mA and 100-mA low drop-out voltage linear regulators (LDOs) simplify board layout.  For digital multi-media applications requiring higher current, TI offers the TPS65262-1 with integrated 350-mA and 150-mA LDOs.

Availability, packaging and pricing

The triple synchronous converters are available in volume now from TI and its authorized distributors. Packaged in a 32-pin QFN package, the TPS65261 is priced at US$1.90 and the TPS65262 is priced at US$2.05 in 1,000-unit quantities. Order a TPS65261EVM or TPS65262EVM evaluation module.

Designing Robust 5G Power Amplifiers for the Real World

Sponsored by Keysight

Simulating 5G power amplifier (PA) designs at the component and system levels with authentic modulation and high-fidelity behavioral models increases predictability, lowers risk, and shrinks schedules. Simulation software enables multi-technology layout and multi-domain analysis, evaluating the impacts of 5G PA design choices while delivering accurate results in a single virtual workspace. This application note delves into how authentic modulation enhances predictability and performance in 5G millimeter-wave systems.
