DALLAS, March 19, 2013 /PRNewswire/ -- Expanding its line of energy-efficient, no-load adapter power controllers, Texas Instruments Incorporated (TI) (NASDAQ: TXN) today announced the industry's first flyback controller that exceeds Energy Star 5 standby power requirements for 10- to 65-W AC/DC adapters used with notebooks, motor control, smart meters, micro-inverters and other high-powered applications. Used in conjunction with TI's award-winning WEBENCH® online design tool, the LM5023 flyback controller simplifies and speeds high-voltage DC/DC designs. For more information, visit: www.ti.com/lm5023-pr.
TI is demonstrating the LM5023 in its booth #109 at the Applied Power Electronics Conference and Expo (APEC) in Long Beach, Calif.
TI's new LM5023 isolated quasi-resonant pulse-width modulation (PWM) controller with integrated 700-mA driver offers high efficiency at up to 90 percent, low EMI and less than 10-mW of standby power. The LM5023 provides 1-percent accurate output voltage regulation, eliminating the need for cable compensation. When coupled with the highly accurate LMV431 shunt reference, it provides a competitively priced, 1-percent accurate flyback controller system.
Key features and benefits of the LM5023:
High-efficiency adapter power
Adapter power products from TI, including the LM5023, UCC28710, UCC28710 and UCC24610 primary and secondary PWM controllers, provide reliable, efficient, low-cost power solutions for a wide range of AC/DC charger and adapter applications. Innovative, high-efficiency power management controllers reduce both energy consumption and solution size. Universal charge controllers help designers minimize environmental impact and reduce charging times with standards compliance. With or without wires, TI solutions provide best-in-class no load power performance and highest average system efficiency.
Availability and pricing
Samples can be requested today and production quantities of the LM5023 are expected to be available in the second quarter. Offered in an 8-pin MSOP package, the LM5023 is priced at US$0.38 in quantities of 1,000.
The LM5023EVM notebook adapter evaluation module is priced at US$49.99 in 1,000-unit quantities and is expected to be available through TI's eStore this quarter. TI also offers a 3.5-W multi-output adapter reference design, that generates an isolated 3.3-V output at 200 mA from an input of 100 V to 250 V.
