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.
