TI's smart AC/DC linear regulator achieves breakthrough in efficiency and power density

The industry's most integrated linear regulator delivers 75 percent efficiency and provides two times more power density than other linear regulators

DALLAS, March 18, 2019 — (PRNewswire) —  Texas Instruments (TI) (NASDAQ: TXN) today expanded its broad portfolio of over 500 linear regulators by introducing a first-of-its-kind smart AC/DC linear regulator. With 75 percent higher efficiency and two times the power density of other linear regulators, this device achieves the best balance between high efficiency and ultra-low noise while shrinking power-supply size. The fully integrated TPS7A78 linear regulator uses a unique switched-capacitor architecture to eliminate discrete components, including external inductors and transformers and miniature circuit breakers and interrupters, for tamper-resistant designs in applications including electronic metering in grid infrastructure and building automation. For more information including samples, see www.ti.com/TPS7A78-pr.

TI will demonstrate the TPS7A78 linear regulator in booth No. 511 at the Applied Power Electronics Conference (APEC) in Anaheim, California, March 18-20, 2019. Read a short article about the newest innovations in power from TI at APEC, such as new products and end-to-end power-management system solutions including hardware, software and reference designs that can help engineers get to market quickly.

The TPS7A78 is a nonisolated linear regulator that delivers up to 0.5 W from AC to DC with smaller, fewer components. This smart design optimizes regulation through an active bridge, switch capacitor and integrated low-dropout regulator (LDO). This design results in higher efficiency and a reduced capacitor size compared to linear regulators in traditional capacitor-drop solutions utilizing a Zener diode. To learn more watch the video, " What is a smart AC/DC linear regulator?"

Key features and benefits of the TPS7A78

Availability, packaging and pricing
Available through the TI store and authorized distributors, the TPS7A78 is offered in a 14-pin, 5-mm-by-6.5-mm thin-shrink small-outline package (TSSOP) and priced in small reels at US$1.00 in 1,000-unit quantities.
